Tracing the paths of two South Dakota war heroes

By Paul Higbee
In April 1942, South Dakotans Henry (Hank) Potter and Don Smith were key players in one of history’s most daring military feats. Half a century later another South Dakota native, Curt Hills, traveled halfway around the globe to trace their adventure, finding both physical remnants and Chinese citizens who were part of this World War II adventure.
The 1942 operation was the famous Doolittle Raid, where 16 U.S. Army Air Corps B-25 planes struck back at Japan, 134 days after that country’s military bombed Pearl Harbor in the Hawaiian Islands. The American raid has often been cited for providing a tremendous morale boost for the United States, facing a real possibility of losing the war as it engaged strong foes in both the Pacific and Atlantic oceans. But historians note that the Doolittle Raid also stunned Japanese citizens who believed their home island to be immune to air attack because it sat isolated in a wide sea. Japanese leaders were forced to realign their far-flung Imperial Navy fleet to better protect the homeland, which created an advantage for America and its allies later in the war.
The air raid was planned and led by Lt. Col. Jimmy Doolittle, a California-born aviation pioneer who set well-publicized airplane endurance records in the 1920s, experimented constantly in hopes of improving aircraft safety and efficiency, and who, against long odds, in the 1930s convinced the Army to switch to higher octane fuels to increase engine power. As it turned out, Doolittle would use every drop of his high-octane fuel for the raid that bears his name. In fact, he would have been better off with a few more ounces.
Doolittle’s B-25 dropped four bombs on Tokyo industrial targets at about noon on Saturday, April 18, 1942, and then swooped low and sped west to escape Japanese air space. In escaping, he credited his navigator — Hank Potter — for plotting “a perfect course.” Potter grew up in Pierre, and then attended Yankton College.
Potter lived long enough for Hills, part of the group who traced the raid, to meet and travel with him. “He was very honest, sincere and caring,” Hills says. “He had those qualities that made it easy to believe he came from South Dakota.”
Don Smith, the other Doolittle Raider from South Dakota, mirrored those qualities. “A straight arrow,” recalled his flight engineer, Edward Saylor. Smith, a pilot, was born at Oldham in 1918, spent most of his childhood in Belle Fourche and graduated from South Dakota State College (now SDSU) in Brookings after winning football’s Little All-America honors as Jackrabbit center. His B-25, dubbed TNT by its crew of five, dropped bombs on Kobe factories more than an hour after Doolittle hit Tokyo.

What baffled Japanese leaders (and the general public in the United States) for months was how 16 B-25s got into Japanese skies in the first place. The closely guarded secret was that Doolittle and Army brass decided the attack was worth risking something that had never been attempted: launching fully loaded medium bombers from the deck of a ship, the carrier Hornet. “It was such a bold plan,” recalled George McGovern, South Dakota’s long-serving U.S. senator who was just preparing to enter the Air Corps himself. “I don’t think anyone but Americans would have tried it.”
Taking off from a carrier meant pilots had to use less than 500 feet of deck instead of 1,000 feet of runway, as was typical on land. Smith practiced steep-angled takeoffs on land in Florida. At sea on April 18 he used fewer than 300 feet of deck — the best mark of the day. In fact, it can be said Smith flew a perfect mission: a takeoff that military aviators could only have imagined weeks before, finding and hitting his industrial targets and executing a smooth water landing 13 hours after launch.
Still, nothing went exactly according to plan that day. After a Japanese trawler spotted the Hornet, all planes took off early, adding 600 miles to their flights. That meant they could get to the safety of China after their bombing runs thanks only to a stout east-to-west tailwind and the quality fuel for which Doolittle had argued.
The Raiders soon learned that China wasn’t as safe as they had hoped. No lighted airfield or fuel awaited the planes on April 18, either because of a communications mix-up or because the Nationalist Chinese government grew leery of helping Americans in the face of likely Japanese revenge. Like the United States, China was at war with Japan, and Japanese troops controlled sections of the country. The American pilots had little choice but to parachute out of their planes with their men or make crash landings (although one crew drew Doolittle’s ire by landing in Siberia where the Soviets seized the B-25).
Potter, Doolittle and the rest of the Plane One crew bailed out into the pitch-black night and survived. Smith approached the China coast, sensed his plane didn’t have enough fuel to climb over a coastal mountain range and made a remarkably smooth sea landing a few hundred yards from Tantou Island (also known as Tantouschan, just off the coast of China). He and his crew had eight minutes before the TNT began sinking, which was time enough to climb out while pulling an inflatable raft with them. After two hours in the water they got to the beach with a cold wind piercing their flight uniforms. Eventually they found shelter in a livestock pen before the Ma Liagshui family spotted the men and invited them into their nearby hut.
Of the 75 Americans who attempted to leap or crash into China that night, one died due to a parachute malfunction, two drowned and eight were quickly captured by Japanese soldiers. The two South Dakotans, along with their 62 scattered peers, made their way hundreds of miles cross country to the Nationalist China capital of Chungking with help from Chinese friends — many of whom later died at the hands of vengeful Japanese soldiers. Potter recalled that he, “walked, went in rickshaws, sedan chair, rode a horse, went on a boat in the river, some sort of car, a so-called bus which was a truck we sat on, a train and finally a C-47 airplane at Chung-king.”

Smith, to his great credit, took a detour on his route to Chungking. Through Chinese guides he learned the crew members of Plane Seven had been badly injured in their crash landing and were in a little hospital at Linhai. The raid’s flight surgeon, Dr. Thomas White, flew aboard Smith’s plane, and Smith decided he had to get White to Linhai over rugged foot trails. There can be absolutely no doubt that White saved Plane Seven pilot Ted Lawson’s life.
Smith returned home on leave in time for Belle Fourche’s Fourth of July rodeo, an event he loved growing up. Sadly, he died later in 1942 in a plane crash in England. Potter went on to a distinguished Air Force career, rose to the rank of colonel, and was commander of Bergstrom Air Force Base in Texas when he retired in 1970. He often made time to attend the famous Doolittle Raiders Reunion each April and took a lead role in organizing the 1978 reunion in Rapid City.
A few years after the reunion in his home state, Potter met Bryan Moon. As a boy growing up in England during World War II, Moon befriended American airmen stationed there, and developed a fascination for their planes. He grew up to become a Northwest Airlines executive based in Minneapolis and an acclaimed artist, specializing in aviation scenes. One of his paintings depicts what he guessed Smith’s TNT might look like beneath the China Sea.
The late Moon was also a true adventurer, willing to spend whatever it took to track down military history and, through an organization he founded called MIA Hunters, the remains of combat casualties interred overseas. In 1990 he led an expedition into China to find Doolittle Raid artifacts and organize ceremonies where brave Chinese people who helped the raiders could be thanked. Curt Hills — born in Chamberlain, raised in Mitchell and by then part of a real estate management group in Rochester, Minnesota — heard Moon speak at a Sertoma Club event. Hills decided he wanted in on the adventures. So did fellow South Dakotan Hank Potter, who represented the Raiders in thank-you ceremonies.
Moon and his fellow travelers met a woman named Zhao Xiaobao who, living on Tantou Island in 1942, helped hide, feed and clothe Smith and his four crewmates. She said her son, a fisherman, knew the exact location of the TNT because he had pulled up small scraps of aircraft metal. Also, islanders had noticed occasional oil slicks there. Moon contacted Smith’s copilot, Griffith Williams, and by Williams’ calculations the crash site matched the fisherman’s description.
But it wouldn’t be easy for Moon’s group to gain access. The island sat near a submarine base in a zone controlled by the Chinese military. Still, Moon wrote to request permission to dive, photograph and videotape. His request gained a boost when Gen. Jimmy Doolittle, in his 90s, wrote to the Chinese government endorsing Moon’s project. Permission was granted in September 1993 — the same month Doolittle died — and Moon dashed to organize an expedition the following April.
The Rochester Post-Bulletin wrote that Smith’s plane, “might be World War II’s most treasured aviation artifact.” Moon told the paper that, “the ideal scenario is we find the airplane in an ideal position,” meaning a wing might extend to within 15 feet or so of the surface. The worst scenario was that nothing would remain beyond a “pile of nuts and bolts.”
Moon’s group of 19 traveled to Tantou Island, 150 miles south of Shanghai, the next spring. Hills noted the island, in some ways, hadn’t changed much since Smith saw it. Its people mostly lived in poverty, eking out livelihoods through fishing and small subsistence farming. Moon’s group learned that a hill up from the beach where the TNT crew climbed to find shelter was actually more of a cliff.

Moon had arranged for a retired military vessel that was positioned over the crash site and used sonar-equipped sensors to create images of what sat beneath. He brought expert divers from the United States, but, Hills says, “diving was quite dangerous. Very strong currents swept divers away. And we learned the plane is submerged much deeper than we expected.”
It is, in fact, about 50 feet beneath the surface. Local islanders had guessed about 30 feet. No part of the TNT extended close to the surface. While the plane is much more than a pile of nuts and bolts, Hills says, “it’s in deep mud and has been beaten by typhoons through the years.”
Raising the TNT was never discussed with the Chinese government in the 1990s, and the 1994 expedition proved that to be unfeasible in the future. Don Smith’s famous warplane will rest underwater until, in coming years, it is indeed a pile of nuts and bolts.
Hank Potter died at age 83 in 2002. His New York Times obituary mentioned a reunion in the 1990s with Zhu Xuesan, an English-speaking man who came to his rescue the morning after he parachuted into China. The reunion happened thanks to Moon’s group. “To be able to meet the man who helped me so much when I was wandering and tired and cold,” said Potter, “it’s just amazing.”
Don Smith didn’t live to attend Doolittle Raiders reunions or to understand how deeply his adventure touched Americans for decades. But 2019 has been a good year for him. The South Dakota Historical Society Press published a new biography called First Strike: Doolittle Raider Don Smith. And in April, Dick Cole — the last surviving Doolittle Raider — accomplished something meaningful just before his death at age 103. Cole kept in his possession one of 80 Congressional Gold Medals, struck for the families of each Raider. No one ever claimed Smith’s, whose widow and only daughter had passed away. Cole wanted the medal to go to South Dakota as a gift from him. With help from Sioux Falls author, filmmaker and aviation artist John Mollison, and others, the medal was delivered to the South Dakota Air and Space Museum, near Rapid City, on the raid’s 77th anniversary. Though Smith’s TNT will forever lie at the bottom of the China Sea, a tangible reminder of South Dakota’s role in one of the world’s most fearless military missions had come home.

Nut trees can flourish in a sliver of South Dakota, but will their growers ever be more than hobbyists?

By John Andrews
Dan DeBuhr was 6 years old in the early 1960s when his grandmother returned from a vacation in Texas with two pecan trees. She planted them in the backyard of her Elk Point home — the same patch of land where DeBuhr lives today — not knowing what to expect. “They told her they couldn’t guarantee that they would make it in South Dakota,” DeBuhr says. “And they would never bear fruit.”
Today, motorists passing by on Interstate 29 can easily spot them because they are the tallest trees in town. In fact, measurements taken last June confirm that they are the two biggest pecan trees in South Dakota, both supplanting a 61-foot pecan in Rapid City.
A severe thunderstorm pelted Elk Point with baseball sized hail early last summer, greatly diminishing the year’s pecan crop. But near the end of most Septembers, DeBuhr wages a daily battle with squirrels to collect the prized nuts. The little critters clearly collect their share, evidenced by the tiny trees that spring up from pecans buried around his yard.
We think of more temperate places when we think of pecans, but they have a history in South Dakota. Pecans — as well as hickory, chestnuts, heartnuts, butternuts, English walnuts and maybe even pine nuts — can indeed grow in certain parts of South Dakota, and experimenters are working to create the best varieties for our environment.
*****
South Dakota is not a robust nut-producing state. Black walnuts are the only nut trees considered native, but John Ball, a professor at South Dakota State University in Brookings, says you can find butternut, American chestnut, English walnut, Manchurian walnut and even pecan, though the growing season is not always long enough to produce nuts. Far southeastern South Dakota, however, is another story.
“It is an unusual part of the state,” says Ball, who is also an SDSU Extension forestry specialist and South Dakota Department of Agriculture and Natural Resources forest health specialist. “We should call it Western Iowa/Northern Nebraska, not South Dakota, and then it would fit. Growing pecans in those states would not be surprising, and southeastern South Dakota is kind of an extension of that. But it’s a rather abrupt line as we move out of there as to where something grows, where something’s a shrub and where something just never makes it at all.”
Our native black walnut provides a good example. “Black walnut is only native to eastern South Dakota, and really the southeast, though there is one population up in Codington County,” Ball says. “But it will even grow in Harding County. I’ve seen some trees out by Union Center and Bison. The difference is the ones down by Yankton and Vermillion can get a couple feet in diameter and 70 feet tall. The ones up in Bison get about 6 inches in diameter and maybe 20 feet tall. So while they can grow there, they grow very slowly. Down in the southeast, you can grow most of the nut trees that can grow out East, though not always as productively and not as quickly. And you have to really work at it. It doesn’t come easily.”
Any discussion of trees and plants and where they might succeed brings to mind the USDA Plant Hardiness Zone Map, the reference that many gardeners consult before planting. The map is based on a region’s annual average extreme minimum temperatures, with lower zone numbers coinciding with colder temperatures. Much of the northern half of South Dakota lies in Zone 4b (-25 degrees Fahrenheit to -20), though some pockets, including Aberdeen, fall in 4a (-30 to -25). The southern half is largely 5a (-20 to -15), with some areas of 5b (-15 to -10) west of Yankton and around the Black Hills, including Rapid City.
But the map may be irrelevant. Ball says the more important factor for nut trees is the number of frost-free days. “I recommend throwing the zone map out when you get to South Dakota,” Ball says. “The zone maps were first developed in Boston. They started drawing the lines back in about 1927, and they did it without ever coming to South Dakota. The real difficulty is it is based upon only one climatic factor: the annual average extreme temperature, or, essentially, how cold it could get in January. That doesn’t do well here, because what really affects our nut production is our early frost in the fall, late frost in the spring, that cold snap that occurs in April after it’s already been warm or a nice mild fall and then suddenly the temperatures fall to freezing.”
The native range of pecan trees stretches from east Texas and Louisiana up through Oklahoma and Arkansas into portions of Missouri, southern Illinois and southern Indiana. They tend to follow river valleys, extending as far north as the Iowa/Illinois line along the Mississippi River. Those areas are most likely to give pecan trees the minimum 140 frost-free days needed for nut production. In South Dakota, those conditions are most likely to be replicated in the southeast.
Perhaps that’s why the DeBuhr pecan trees have flourished in Elk Point. Three more pecans purchased from Gurney’s Seed and Nursery in Yankton in the mid-1940s tower over Rick Gray’s home just north of Dakota Valley High School near McCook Lake. And Ball knows of a few pecan trees in Sioux Falls that produce nuts every few years. “While we do define areas and which trees will grow and perform well there, no tree has ever read a book,” Ball says. “We always get the outlier, the tree that’s growing where it shouldn’t, yet performing better than anyone would ever expect. And that’s the fun of South Dakota. It’s not like trees grow everywhere, and you really appreciate it when they make it.”

John Goeden is an agronomist and self-described “collector of cultivars.” When he’s not consulting on corn and soybean hybrids for Channel Seed, he’s tinkering with trees on his 1.8 acres just west of McCook Lake. “My dad was a carpenter, and he loved hardwood trees, particularly walnut,” Goeden says. “That’s probably where it all started. I helped him take out a grove of about 100 walnut trees that were going to get ripped out of the ground and farmed in the late ‘90s. So in some ways, I’m paying for the sins of my father — and myself.”

He is particularly interested in pecan and hickory trees. He believes hickories were a prominent part of the river valley landscape until homesteaders began flooding the Plains in the 1860s. “We had a huge mass migration of people from east to west, and they came in wagon trains made of wood and iron,” he says. “When they were making and repairing things, they were all looking for the straightest, hardest, most durable wood they could find, and hickory was it. That’s probably a reason why we don’t have a lot of hickory remnants left. It’s also the best firewood.”
Historically, the Lakota were familiar with hickory from their time living in eastern Minnesota, before they were pushed west. Similarly, many Great Plains tribes had a word for pecan. “That means that they were either trading in pecan or making trips to where they were plentiful, which would be eastern Iowa, Illinois and Missouri,” he says. “They knew pecan.”
Those species command most of his attention. By the summer of 2024, Goeden’s experiments with tree grafting had resulted in at least 25 different pecan cultivars, along with 15 hickory and four English walnut.
Grafting is a tricky process by which two trees are fused together. Scion wood from a donor tree is cut and attached to rootstock so that their corresponding layers of cambium — the main growth tissue located just beneath the bark — align. The graft is then tightly wrapped and kept moist until the tissues begin to grow together.
“We’re probably not going to extend the harvest to Timber Lake,” Ball says. “But they’re trying to improve the quality of the nut. The rule of thumb I always use is the better the nut, the less chance it has of growing here. You’ve really got to work to develop those qualities, and grafting is how we do it. Thank goodness for the hobbyists that are doing that work to help push the limits and extend the higher quality nuts to our area.”
It was a failed graft that led Goeden to learn about the process. “I had planted some English walnuts,” he says. “I had them in the ground nearly 20 years and they produced nuts. Well, if you look at the leaflets you can tell the difference between an English walnut and black walnut. Somewhere along the line — either before I got those trees or perhaps after — the graft died back, and the black walnut took over. That’s what I actually had.”
His interest in grafting led him to the Nebraska Nut Growers Association, an organization that since the early 1970s has worked on grafting nut trees and placing them in the northern landscape. Grafting is particularly beneficial when working with nut trees, because it can dramatically reduce the time it takes to bear fruit. Self-pollinated pecan, oak and walnut trees might not produce nuts for 15 to 20 years. A hickory might take 40 years. “But if you take wood from a pecan tree and attach it to a two-year seedling and it takes, chances are in eight to 10 years you can have a pecan in your hand,” Goeden says. “It takes the memory of that tree it was on and puts it on top of a seedling. It basically cuts the time in half.”
Grafting and selected cross pollination have resulted in dozens of pecan cultivars, each with different nut sizes, bearing times, percentage of nut meat within the shell and cracking ability. Goeden is growing several of them in his backyard. “My goal is to see what we can effectively grow here and what we can’t,” he says. “Pecans and hickories can grow here, and we’ll find out which ones will survive. I’m trying to get the biggest, best nut possible, and the way to do that is to look at a number of cultivars in your own environment.”
Several of Goeden’s grafted cultivars are growing on Darrell and Martha Ausborn’s 10 acres of land west of Yankton overlooking Lewis and Clark Lake. Ausborn is a retired forester who began in private industry in Florida and Alabama. He later transferred to the Bureau of Indian Affairs where he worked as a forester until retirement.
He and Martha, an Alabama native, chose the Yankton County acreage because, Martha says, “he needed a place to play.”
To stay busy in retirement, the couple set their sights on nut trees. In 2008 they planted a batch of grafted seedlings that included English walnut, black walnut, pecan, Chinese chestnut, heartnut and butternut. As they’ve experimented, the Ausborns have added cultivars from various nurseries as well as grafted cultivars from Goeden.
“For pecans, we’re about as far north as you can get,” Darrell says. “The trees do okay, but some years there aren’t enough summer heat days for the nuts to mature. Last year they did mature, and this year they are growing. We’ll see how far they make it into the fall. If we get a cool September or an early frost, the pecans won’t be there. But the rest of the nuts do produce.”
A visit to the Ausborns’ grove in early August found healthy hazelnut trees, the nuts still tightly wrapped within flower-like green husks. “You have to hunt for the hazelnuts,” Martha said as she searched the branches. “I like to pick them because it’s like looking for Easter eggs. They lay up underneath the leaves. The husk has to dry and turn brown, and the nut will be loose. When you can touch it and it will spin, usually the last week in August, that’s when you can harvest.”

The Ausborns also boasted healthy crops of heartnuts, butternuts, English walnuts and Chinese chestnuts. A Korean pine nut tree looked somewhat out of place but seems to enjoy the Yankton County environment. “That was something out of pure curiosity, just to see if it would grow,” Ausborn says. “In about 30 years you might be able to taste a pine nut, so remember it’s here.”
*****
Nut harvests are modest. The Ausborns spend fall days using homemade equipment to gather, wash and shell their assortment of nuts. Goeden shares his pecans and other nuts with friends and family. They gather every winter with the Nebraska Nut Growers Association for an annual nut evaluation that measures each nut’s size, cracking ability, flavor and quality and quantity of nutmeat. The results help them determine what cultivars are working.
They are also willing to help others. “Without the knowledge and expertise of the Nebraska Nut Growers Association, Darrell and I wouldn’t have had the success that we’ve had,” Goeden says. “Grafting nut trees is an fading art that needs to be passed from one generation to the next in order to push yield potential.”
People like Goeden and the Ausborns will never grow rich from nut production. Ball says a commercial operation in South Dakota is likely not viable. Still, with the right trees, bags of South Dakota-grown hazelnuts or pecans could show up at farmers’ markets and craft fairs. “It’s kind of like farming has gone,” Ball says. “When I was a kid, a family of five could live on a 140-acre mixed farm. Now that’s a hobby farm. Nut production is the same way. It’s hard to get the scale to where you’re actually able to make a living out of it as opposed to supplementing your income. But for a supplement, yes, you can have a hobby that actually pays.”
Dan DeBuhr’s grandmother likely never thought of her tiny pecan trees as a profitable side hustle, but she loved all trees and encouraged her grandson to care for them long after she was gone. “My grandma told me, ‘I’ll never be able to see the pecans, but if you stay here long enough, you probably will,’” DeBuhr recalls. “‘Do me a favor,’ she said. ‘When the trees get big, take a chair on the hottest day, when there’s no wind, and go sit under the trees, because they’ll talk to you.’
“One day in July I was out here working, and it was so hot, no air. So I got a chair and put it right between those trees. All of sudden the leaves were just shaking. That’s what she meant by talking.”
Perhaps they were saying they belong here after all.

The most claustrophobic experience on water

By Katie Hunhoff
Boaters and adventurers often shy away from the shallow delta that is overtaking the Missouri River by Springfield in southeast South Dakota.
They worry about snags and stumps in the water. The ever-changing channel is confusing. Dozens of sandbars create a maze, and in many places the swamp grass is 10 feet high, making it impossible to see the hills of the shoreline that could provide bearings. Water depths vary from 12 feet to less than a foot.
Snakes, snapping turtles and other critters add to the mystique of a place like nowhere else in the American West.
We wouldn’t explore the delta with just anyone, but Greg Stockholm seemed reliable. Stockholm knows and loves the rivers of America. The tall, cheerful 67-year-old has boated much of the Missouri and Mississippi, as well as the Ohio and numerous other lakes and waterways.
But he’s especially at home on the delta. He boated the Missouri with his dad as a boy, when the reservoir known as Lewis and Clark Lake was sparkly new. Water then extended from shore to shore — more than a mile wide and deep enough for him and his friends to experiment with five-man pyramids on water skis. In 1977 he was skiing with a kite on Lake Poinsett when it sailed skyward and dropped him hard on the water. He was hospitalized for eight weeks, but he was back in a boat almost before his injuries healed.
As a youth, Stockholm watched his father, Alfred, build a 21-foot cabin cruiser. His earliest memories are of taking the wheel of the cruiser at age 4. In 2022 he began construction of a 72-foot sailboat that he hopes to launch near Sioux City, Iowa. His plan is to motor the boat to the ocean, raise its 80-foot mainsail and set off across the Atlantic.

Stockholm has operated a body shop for most of his adult life. In his spare time — between fixing cars and building the big sailboat — he still found time to restore a classic 1975 Tahiti jet boat with a 389-inch Pontiac engine.
“Half the boats around Springfield never get in the water here,” he says, because the owners are leery of the delta. We climb aboard the Tahiti at the boat docks on the east side of town. The big engine rattles to life, sending vibrations throughout the little black craft.
Just as we leave the docks and enter the delta, Stockholm points to the Eagle depth finder below the steering wheel of the Tahiti. It reads 6 feet.
“We’re in the main channel right here,” he says.
But then we enter a water alley between two sandbars and the big engine sputters. The propellor has hit sand. The Eagle says we are in a foot of water.
It’s not a problem. Stockholm shifts to “R” and we reverse into a few feet of water.
We’d imagined a delta of grassy sandbars with frogs, toads, crawdads, crabs, flying insects and patches of brackish mud. That’s not the South Dakota delta.
The water seems clean and fresh and there is little mud. It’s mostly sand below the water and on the islands or sandbars. Growing on nearly all the sand is a tall perennial grass called phragmites, an invasive species that is spreading to lakes and wetlands throughout eastern South Dakota. Unfortunately, it creates a dense, nearly impenetrable jungle that deer and other wildlife try to avoid. Phragmites even affects fish because the massive roots dry the marshland and reduce habitat for minnows, frogs and other small creatures.
Stockholm says the U.S. Corps of Engineers, overseer of the Missouri River valley, sends helicopters with herbicide sprayers to attack the phragmites infestation in the Springfield delta. Once the reeds die and turn white, the federal authorities sometimes burn the sandbars. Their goal is to eliminate all vegetation on the sandbars so the endangered piping plover will have better nesting conditions.
It would be nice if the herbicide, which has been approved for aquatic use by the EPA, would enable cattails, Russian olives and wild grasses to regain a foothold, but on our trip through the maze it appeared that the phragmites are winning the war with the Corps.
We saw few signs of wildlife. A lone deer peeked out of the reeds. A massive old snapping turtle, 2 feet in diameter, balanced on a stump in the water.
Stockholm says the river has quieted in his lifetime. “I remember lying awake in bed in our house in town and hearing the honking of geese all night long,” he says.
The throaty baritone of bullfrogs was a regular sound of summer. Beavers, muskrats and other wildlife added to the cacophony of the river. On our outing, there was nary a sound when Stockholm shut down the Pontiac engine.
Still, he says, this is a wild place. “The river is alive. You can never outguess it. It’s always changing, and it probably always will be.”
Two main channels of the old river can be found in the delta, one on the South Dakota side and another below the yellow chalkstone bluffs of Nebraska.
Stockholm sped up the Tahiti for a 7-mile zig-zag journey southwest on the river to the little fishing village of Running Water. Phragmites are there, too, lining the shore by the boat docks. Just beyond Running Water is the Standing Bear Bridge, a 3,000-foot crossing that gives motorists an expansive view of the delta.
West of Running Water is the town of Niobrara, Nebraska, and the mouth of the Niobrara River, which brings several million tons of sediment into Lewis and Clark Lake every year — creating the unusual delta that is slowly creeping eastward. Experts predict that the grassy delta — with its phragmites-laden sandbars — could reach Gavins Point Dam at Yankton if an affordable solution isn’t found.
The sediment is considered a scourge in South Dakota and Nebraska. Ironically, it is badly needed in the Gulf of Mexico where the coastline is disappearing due to erosion and rising sea levels. Before the six dams were built on the Missouri River in the 1940s and 1950s, sediment from the 2,341-mile Missouri — North America’s longest river — flowed unimpeded to the Gulf.
Now it lays above Gavins Point Dam.
Upon reaching the Standing Bear Bridge, Stockholm steered the Tahiti northeast and motored back toward Springfield. Moving with the current, the big motor had easy work. The sun was now at our backs and setting low over the delta. Blue herons began to show up along the shore. Sometimes, the graceful birds craned their long necks and stared. Just one other boat was on the water that night, so we were a rare sight. A curious crane took flight and followed us down the river.

“Sometimes I think they want to race the boat,” grinned Stockholm.
Other waterfowl appeared at sunset. A small flock of Canada geese flew in formation from the east.
When we arrived at Springfield, where we’d begun, Stockholm asked if we wanted to see where the delta ends and “the lake begins.” Of course, we did.
So we traveled east just a few miles — past another fishing village known as Apple Tree. A flock of perhaps 50 big white pelicans sat on a shallow ledge.
Stockholm pointed to the Nebraska shoreline, about a mile and a half away, and said he’s quite sure we could walk there. “I doubt the water is more than waist high all the way across.”
If the sediment continues to fill the lake, scientists say the delta will extend all the way to the Yankton dam, 15 miles away. The tallgrass phragmites will surely follow.
We rounded a sandbar and there was open water as far as we could see to the east — a fresh sight after spending hours in the claustrophobic delta.

The May/June 2026 issue of South Dakota Magazine features a story on the few tall grass prairie remnants remaining east of the Missouri River. When I was asked to help illustrate the story, I was surprised by how many photos I have taken in and around these places.
I grew up in short and mixed grass country along the Dewey and Ziebach county line west of the Missouri. Only in wet areas or in wet years did the grass get so high that you couldn’t see where your boot fell, which is an important thing in rattlesnake country. When I first began exploring the tall grass preserves with camera in hand, it was unnerving to not be able to see the ground below … and whatever sinister critters may be lurking. Turns out plenty of creatures call the tall grass home. My favorite are the colorful and elusive butterflies. From monarchs to tiny eastern-tailed blues, I have been known to spend hours on the trail seeking that perfect close-up shot.
I also discovered the beauty of the grass itself when peering through my macro lens at blooming sideoats grama florets at the Sioux Prairie Preserve near Colman. Big bluestem, cordgrass and many other tall grass regulars all flower during the summer and photographing them can be nearly impossible due to the wind that we regularly endure on the Northern Plains. To be honest though, a good breeze is welcome in that it keeps the gnats and mosquitos mostly at bay. Yep, it’s not all butterflies and flowers in tall grass country. Myriads of insects live there and a good breeze plus insect repellent is a must when exploring.
After gathering photos for the article, I was asked to gather again for a flyer promoting the new prairie grass area at Good Earth State Park. As I waded back into the archives, I noticed the crescendo of forays into tall grass preserves started slowly about 10 years ago and reached full throat when I was challenged to find and photograph the elusive green orchid. Until that point, I thought wild orchids only grew in exotic tropic locales. Thankfully, I was wrong. South Dakota is home to over 20 orchid species depending on who’s counting. The tall grass preserves are a haven for these beauties and their allies, all of which are a paradise for a camera guy with a macro lens.
Earlier this month, I was out finding the season’s first pasque flowers in the Coteau Hills overlooking Jacobson Fen in Deuel County. As I got up close to frame a few fuzzy portraits of our state flower, I got the idea to share these new photos along with a few other tall grass favorites I had gathered but did not make the final printed story. I hope they convey the sense of wonder and enjoyment I get while out roaming the tall grass remnants.
