Winter Potatoes

Silcrete rocks, unique in North America, dot the pastures around Ludlow in Harding County.

When we were growing up on our ranch near Ludlow, we called them flint rocks, though an old timer wittily referred to them as winter potatoes. They are actually siliceous rocks, formed during the Paleocene Epoch (56 to 66 million years ago), numerous on hills and ridges around Ludlow and quite rare on the continent.

Geologists believe that silcrete formed from siliceous waters (rich in silica, a common mineral) in a swampy environment when the region was warm, humid and covered with vegetation. Rocks are made up of minerals and this silcrete is composed of silt sized grains of quartz in a matrix of microcrystalline quartz. Evidence of ancient stems and roots of plants can be found in the rocks; holes and impressions left by that ancient plant material remain.

The very top layer of Flint Butte (a butte northeast of Ludlow known by locals as Flat Top) is an intact solid layer of silcrete and measures 2 to 3 feet thick. It is hard and resistant to erosion. Over the years, softer underlying rock and deposits eroded away, leaving silcrete material and rocks on the surface hills and ridges. The Ludlow area silcrete deposit has been mapped for 30 miles, from the North Cave Hills to Lodgepole. Similar silcrete beds are found in South Africa and Australia.

The Harding County rocks are between 56 million and 66 million years old.

Native Americans used these rocks to make tools and weapons and to anchor tipis. Large rocks can still be seen hanging on fence posts where opportunistic ranchers used barbed wire to attach them to keep posts from pulling out of the ground. We remember building and fixing fences, and like our neighbors, looked for silcrete rocks with natural holes made by ancient roots. The holes are very useful; barbed wire can be run through, which allows for easy attachment. In fact, evidence of old abandoned fence lines in Harding County can be traced to a trail of rocks. Local landmarks such as Tepee Buttes and Flint Butte are covered with silcrete rocks, and they are very numerous among pastures along Highway 85 about a mile north of Ludlow.

Generations of farmers and ranchers have piled the rocks on the edges of fields and cursed them as they took a toll on their farm equipment. We remember the horrific screeching of a disc blade grating against a silcrete rock and watching towed implements jump into the air when striking one. Many oil pans, differentials and steering components have been scarred and punctured by ranchers and hunters driving across pastures where these jagged rocks were hidden in tall grass. It is a sickening sound when a low-slung vehicle encounters one of these sharp-edged rocks. Many a prairie fire has started when mowers and swathers hit silcrete rocks during dry conditions.

Ludlow’s silcrete rocks are unique in North America with an interesting history and use. They are rugged, windswept, and hardened, like generations of inhabitants who walked these lands.

In Full Bloom

It’s wildflower season again across the Northern Plains. Lately my photography has taken me down the path of botany. Well, not fully, I guess. I’m mostly interested in flowers and florets as well as some of the myriad of creatures that can be found around or among them. That means wildflowers for sure, but also grasses, butterflies and bees, among other things. June and July are prime months to get out and search for these bits of beauty fringing the prairie grass tapestries of our region.

This spring saw good rain for much of our state, and wildflowers follow the rain. When that happens, it is hard not to fall in love all over again with the surprisingly intricate beauty of the open prairie. I was in the Slim Buttes of Harding County and the Grand River National Grasslands in Perkins County in late June. I can’t remember ever seeing more blooms there. Sego lilies, spiderwort, yucca and prickly pear, all came out to enjoy the late spring weather. While looking for pincushion cactus, I came across a new-to-me bloom called clustered broomrape. It does not have any chlorophyll and gets the nutrients it needs from host plant roots, likely sagebrush in this case. I thought plants like these only grew in forests, but the prairie proved me wrong.

Speaking of prickly pear, I don’t usually have many good things to say about that particular plant. I’ve had bad experiences stepping on, falling in or unknowingly putting my hands on this cactus in my formative years. Those are not good memories. I’ve also seen favorite pets suffer tremendously after getting entangled and then feeling awful as one of the folks had to hold it down and pry the quills out. That said, when they bloom all at once on a sunny June day, adding accents of bright colors to the prairies, well I have to say, they grow on you. Such was the sight just south of Shadehill Recreation Area in Perkins County this year.

This is the first year I’ve seen timpsila (prairie turnip) with blooms. This plant was a staple for the Lakota and other regional tribes in an earlier time. Scarlet globemallow (cowboy’s delight) also has an interesting story. In Witness: A Hunkpapa Historian’s Strong-Heart Song of the Lakotas, Josephine Waggoner describes her people rubbing the flower on their hands and arms and then plunging them into boiling water and not getting injured. It was seen as a miracle plant used to alleviate burns, sunburns and even raw skin on a pony’s back.

There is so much to learn and respect about our native prairie habitats. Seeking out and sitting with the wildflowers has taught me much. Hopefully this collection of recent photos will inspire you to take a walk in the high prairie and see what you can learn.

Autumn in the High Country

Autumn always comes early to the high country. While late summer lingers across the rest of the land, the high coulees and upper draws seem to consistently show the first real signs of the season. The last week of September is normally the peak of fall color in places like Spearfish Canyon, the Slim Buttes and even Sica Hollow in the northeast corner of the state. For this reason, I regularly find myself wandering the back roads and trails of the high country every year about this time. It’s not that I welcome the end of summer, but it’s hard not to love autumn around here.

The beauty is fleeting, admittedly. When the weather patterns switch in this season of change, it brings strong winds that rob the trees of their dying leaves. That’s a lesson unto itself. There is beauty in endings. Sad though it is, it helps that there is promise of new life returning after the long winter.

This year I started around Sica Hollow during the golden hour on September 26. I was a bit early for fall color peak, but the color that was showing in the late afternoon and evening light seemed to accent the autumn beginnings quite wonderfully. A couple of days later I hit Badlands National Park, where the upper draws of Sage Creek were brilliant. One thing I learned is that yellow-leaved trees make for interesting visuals in a black and white image. They look nearly white.

After spending a day and half wandering around the Badlands, I made my way for Custer State Park. Needles Highway offers unique autumn color combined with winding roads and sweeping vistas. The fall foliage along the park’s creeks also offers colorful hues. From Custer State Park, I headed to the high country of Lawrence County by way of the Mystic and Rochford roads, finally ending up in Spearfish Canyon by late afternoon. This scenic byway is a must-drive in autumn. One extra perk this year was a small herd of mountain goats grazing near Bridal Veil Falls.

I finished up my tour of the high country in the first days of October by traveling north to the Slim Buttes and Cave Hills of Harding County. These areas are part of the Custer National Forest primarily for their stands of evergreens atop the buttes and hills, but they both offer great stands of deciduous trees along the draws and valleys. These places have become an autumn favorite for me. This year I missed the peak at the Slim Buttes as the color was nearly gone when I passed through, but the Cave Hills were nearly perfect. It goes to show just how fleeting fall’s beauty can be here on the high plains, even within a single county. Even so, the drive and views were worth every minute. The good news is that now the rest of the lower country as well as city and towns should be starting their autumn transformations. So, if you couldn’t make it to the high country, you still have a chance to get out and enjoy the rest of the season.

A Bouquet of Easter Flowers

Sioux Falls photographer and avid pasqueflower hunter Christian Begeman was shooting photos in the Cave Hills last spring when he noticed a mass of pasques gone to seed. This week, he paid a return visit to northern Harding County in the hopes of capturing the delicate purple blooms.”I thought I got skunked, but then I saw a lone purple spot of color on a ridge just beyond the Forest Service Picnic campgrounds and discovered fifty-plus flowers just starting to poke through.” He decided to share those blossoms with us in honor of the holiday. Happy Easter!

Traveling with a Classic Guidebook

An arch that once spanned Highway 12 at Ipswich was moved to facilitate the road’s expansion in 1973. It now stands in a nearby park. Photo by Chad Coppess/S.D. Tourism.

Perhaps the oldest book in my office is a maroon hardcover copy of the South Dakota Guide. Published in 1938, the book was a project of the Depression-era Works Progress Administration. Out-of-work writers were hired to explore the 48 states and compile a travel book for each one, pointing out interesting places along the main-travelled routes.

In the summer of 2018, in honor of the book’s 80th anniversary, we decided to see what remained of the sites chronicled in the original guidebook. Some no longer exist, but we discovered several points of interest that drew the attention of the travel writers of 1938. In this summer of social distancing, perhaps a drive with the South Dakota Guide as a companion might be in order. Original copies of the book are hard to find, but the South Dakota Historical Society Press published a new version in 2005.

Here are a few examples of entries as they appeared in the original guide, along with our present-day observations.

Memorial Hall, Pierre

  • 1938: Memorial Hall is dedicated to South Dakota soldiers and sailors who lost their lives in the World War and houses the State Historical Society, Department of History and State Museum. Constructed of Hot Springs, S.Dak., sandstone, the building is stately and of classic design.
  • 2020: Memorial Hall still stands, though the historical society has moved to the Cultural Heritage Center. The building is now home to the state military and veterans affairs departments.

Graceland Cemetery, Mitchell

  • 1938: Left of the road is the Israel Greene Monument, a large red stone marker bearing the coat of arms of the Greene family — Nathaniel Greene of Revolutionary War fame and Israel Greene who captured John Brown at Harpers’ Ferry in 1859 while a lieutenant under Gen. Robert E. Lee. When the Civil War was over, Israel Greene came to Mitchell as a surveyor, living there the rest of his life.
  • 2020: The cemetery is obviously larger, but it’s easy to find the Greene memorial in Old Part Block II-A.

Highway Arch, Ipswich

  • 1938: The promotion of the Yellowstone Trail from”Plymouth Rock to Puget Sound” was begun at Ipswich by Joseph W. Parmley. A World War Memorial Arch spans the highway, bearing the name of the Yellowstone Trail and its founder.
  • 2020: The arch had to be removed when Highway 12 was expanded in 1973. You’ll find it today in a nearby park.

Main Street, Aberdeen

  • 1938: The site of the drug store in Main Traveled Roads by Hamlin Garland is at the corner of Main St. and First Ave. SE, across from the Alonzo Ward Hotel.
  • 2020: The building across from the Ward Hotel, a downtown landmark since its construction in 1928, is now a law office. Garland homesteaded in Brown County with his parents before becoming a noted novelist.

The Jump-off, Harding County

  • 1938: The Jump-Off is really a fault in earth’s surface extending N. and S. for many miles, the country is much like the Badlands on a smaller scale. It was in the heart of the Jump-Off that Tipperary, South Dakota’s most famous bucking horse, lived his entire life on the ranch of his owner, Charlie Wilson.
  • 2020: Tipperary is still famous in rodeo circles. A life-size bronze of the horse, sculpted by Tony Chytka, stands in Centennial Park in Buffalo.

Washington High School, Sioux Falls

  • 1938: Between Main and Dakota Aves., and 11th and 12th Sts., known as the”million dollar high school,” was constructed of native pink quartzite stone, with the north wing trim and column portico of a black quartzite so rare that it has been occasionally dismantled and exhibited at expositions.
  • 2020: The old Washington High School is now the Washington Pavilion. The black stone is actually Corson diabase, a billion-year-old molten rock that flowed into fractures in the pink quartzite and was mined at Lien Park in northeast Sioux Falls.

Untamed Harding County

Harding County, in the far northwestern corner of South Dakota, is decidedly rural. Buffalo, the county seat with a population of 330, is the largest town. Camp Crook has 100, and smaller communities like Ralph, Reva, Ludlow, Ladner and Harding might have a few ranch families. The county as a whole is home to 1,255 people, making it the second least populated county in South Dakota. Cattle and sheep outnumber people almost 10 to 1, and the most legendary stories are about a killer wolf with three toes and a rambunctious rodeo bronc that has been memorialized in bronze. Still, Harding County’s unique geography and history have drawn curious travelers and explorers for centuries.

It began even before there was a Harding County. The place was created in 1881 and named for Dr. John A. Harding, a dry goods merchant and postmaster from Deadwood who was also serving as Speaker of the House in the Dakota Territorial Legislature. Harding County merged for a few years with Butte County, its neighbor to the south, then became separate again in 1909.

On his gold exploring expedition to the Black Hills in 1874, Gen. George Custer heard stories from a Lakota guide named Goose about unique drawings etched into canyon walls. Goose brought him to the Cave Hills north of present day Buffalo, which boasts several petroglyphs dating back thousands of years.

There are drawings of bison, antelope, a warrior and spear and others even more difficult to discern because of their age and the effects of weathering. A member of the expedition is thought to have carved his initials into a rock wall that also bears the image of a large body shield and weapon. Names and initials of 20th century visitors can be found, too.

Buffalo is the Harding County seat and features a sculpture of legendary bronc Tipperary in the city park.

The Cave Hills are part of the Custer National Forest, pockets of which are spread throughout the county. The section farther to the east contains the Slim Buttes, a blend of badlands, pine forest and mesas that runs 40 miles north to south and stretches 20 miles wide. Local ranchers have named most of the peaks and buttes. There are the Seals, the Three Sisters, Doc Hodges Draw, Adam and Eve Butte and Battleship Rock. Highway 79 crosses Slim Buttes to the south and Highway 20 runs west of Reva.

One of the more spectacular features of the Slim Buttes is the Castles, one of South Dakota’s 13 National Natural Landmarks. The Castles are an L-shaped ridge of bluffs that stretch 30 miles across eastern Harding County. The twin white buttes looming south of Highway 20 contain exposed rock dating as far back as the Upper Cretaceous period (100 million to 66 million years old) through the Miocene (23 million to 5 million years old). The Castles also contain a variety of fossils, but collection is prohibited because they lie within the Custer National Forest.

Their name comes from John Finerty, an Irish newspaperman who traveled with Gen. George Crook’s Expedition of 1876. As they passed through the rugged country, Finerty compared the formation to”a series of mammoth Norman castles.” They look particularly medieval in the morning or evening light, when the white stone shines like polished granite.

The area is also historically important. A memorial and three graves just east of the Castles mark the scene of the Battle of Slim Buttes, a fight between a few hundred Indians and 2,000 cavalrymen in September 1876, just three months after the Battle of the Little Bighorn. After that defeat, Captain Anson Mills was ordered to the Black Hills to resupply. His march took him through the Slim Buttes, the site of American Horse’s camp. Troops surrounded the village of 37 lodges and opened fire. American Horse was shot through the abdomen, but refused help from Army surgeons. He died within days. Locals say you can still see scars from the bullets on ancient trees along Deer Draw Pass. Headstones mark the burial site of three cavalry soldiers who died in the conflict. The graves are east of the Castles along Highway 20.

The Island is a mesa in the Cave Hills that has attracted people for centuries.

Another gravesite in the Slim Buttes is a reminder of South Dakota’s vicious winters. During the notorious Children’s Blizzard of January 1888, Otis Bye, a scout and trapper, was away from home. His wife ventured outside to save their horses. Her frozen body was found days later, watched over by the family dog. Decades later, neighbors erected a gravestone at the site. Find it by driving east of Buffalo on Highway 20 about 19 miles to North End Road. Take a left and drive a quarter of a mile until you reach an old trail. Hike down the trail to the gravesite.

With its abundance of ranches, it’s no surprise that rodeo has had a strong presence in Harding County. South Dakota’s most famous bucking bronc was was born on a ranch by Long Pines in 1905. He bolted the first time a rider attempted to get on his back, so ranchers deemed him unfit for ranch work. Later they tried him as a rodeo bronc. Ed Marty was the first to try a ride and was immediately thrown clear.”It’s a long, long way to Tipperary!” he said, thus giving the horse his name.

For 15 years, 82 cowboys tried and failed to ride Tipperary. Then came the Belle Fourche Roundup in 1920, where Yakima Canutt became the first — and only — cowboy ever to successfully stay atop Tipperary. Despite his victory, cowboys still debated the merits of the ride because rainfall made the arena muddy. Tipperary slipped to his knees and never gained strong footing.

Members of Custer’s 1874 Black Hills expedition are thought to have scrawled initials into this rock wall in the Cave Hills. It also contains an ancient depiction of a shield.

Tipperary died during a blizzard in 1932, but people in Buffalo and Harding County never forgot their star athlete. In 1955 they erected a monument in Buffalo’s city park, and in 2009 the town dedicated a half-size statue done by cowboy sculptor Tony Chytka of Belle Fourche. There’s also an exhibit dedicated to Tipperary inside the Buffalo Museum.

A wild contemporary of Tipperary’s was Three Toes, a gray wolf that terrorized ranchers and sheepherders for 13 years, killing at least $50,000 worth of stock. Legendary sheepherder and writer Archie Gilfillan described the carnage.”Other wolves might kill one cow or sheep and eat off that and be satisfied. But Three Toes killed for the sheer love of killing. He would kill on a full stomach as well as when hungry. On one occasion he visited three different ranches in one night, killed many sheep and lambs at each one, but ate only the liver of one lamb.”

His reign of terror began in 1912, which was about the time he sustained the injury that gave him his name. One of his toes was pinched off in a trap, and from that day the tracks he left in the dirt and snow were as distinguishing as a human fingerprint.

It was estimated that 150 men tried at one time or another to capture him, but Three Toes always seemed to have speed, intelligence and luck on his side. By 1925, he was killing at a rate of $1,000 worth of stock a month. The Harding County Commission raised the bounty on him to $500. A federal hunter named Clyde Briggs, an experienced hunter of gray wolves, came to Harding County and set an elaborate network of traps that extended 33 miles around Three Toes’ favorite ranch targets. On July 23, Briggs descended into the Little Missouri River valley and discovered Three Toes caught in the snares of two traps. He was muzzled and loaded into Briggs’ car but died before they reached Buffalo.

Three Toes and Tipperary are long gone, but their legends, the cattle and sheep, the rugged buttes and mesas, the stone johnnies and 1,200 hearty souls remain.

Caverns Amid the Prairie

The Cave Hills rise from the plains north of Buffalo in Harding County. Its mesas and hills are pockmarked with many cave-like entrances; the best known is Ludlow Cave. Early explorers called the 22,000 lonely acres the “Little Mountains.” Today, wildlife and cattle greatly outnumber human inhabitants. Christian Begeman explored the area this fall.

Beautiful Buttes

Slim Buttes is a mix of badlands, ponderosa pine forest and mesas surrounded by West River grasslands. It runs 40 miles north-to-south and is just 20 miles wide. Most travelers only see the buttes as they climb the high hill east of Buffalo on Highway 20. Looming south of the highway are the Castles, twin white buttes that look like royal ruins. Most of the other peaks and promontories have names, too. Ranchers dubbed one formation The Seals, and another Three sisters. Official names include Doc Hodge Draw, Adam and Eve Butte, Battleship Rock and Government Rock, the highest point. Photos by Christian Begeman.

Stormy Slim Buttes

A photographer’s got to be ready for whatever South Dakota skies bring. Christian Begeman experienced that on his recent West River fall photo trip on September 30.”When I was shooting in the Slim Buttes of Harding County, a cold front swept through and brought brief yet heavy sideways rain and strong wind gusts. I heard later on the news that an 85 mph wind gust was recorded just west and north of where I was in Buffalo. I went out to meet the storm and then chased the rainbow it produced until I got back to the Slim Buttes,” Christian said.

West River’s Fleeting Fall Color

The colors of fall can be elusive in a predominantly prairie state like South Dakota. Our national forests are mostly made up of evergreens. Autumn winds can blow relentlessly through the rest of the trees as winter’s long arm begins to creep down from the north. Wild weather swings, as evidenced by this past week’s brutal snowstorm on the west side of the state and tornados clipping the southeast corner, don’t help autumn’s splendor stay around for long either. To me, fall’s fleeting nature is what makes photographing its beauty so fun and fulfilling.

This year, I was able to break away from the normal routine to spend a few days searching for autumn color. From Sunday, September 29 through Tuesday, October 1, I made a wide circle through some of the prettiest country our state has to offer west of the Missouri. Last year, I discovered that the valleys and draws of the Sage Creek Wilderness offer some unique fall scenes with the Badlands as a backdrop. I got there maybe a week before the trees were in prime color, however, I found that the early morning sun backlighting the leaves brought out fall’s tints anyway.

My next stop was the northern Black Hills. This area contains two of the most scenic canyons in the state and they are particularly beautiful when dressed in autumn’s hues. Vanocker Canyon Road between Nemo and Sturgis is a short but beautiful drive. Spearfish Canyon’s scenic highway is also a must see during this season. At Savoy, you can get out and hike to waterfalls, alongside creeks and nature areas that will take your breath away.

Around a hundred miles north and a little east of the Black Hills is the furthest eastward unit of Custer National Forest. This narrow band of trees grace the tops and sides of the Slim Buttes of Harding County. I have seen and been impressed with other photographers’ images of that area taken in the fall and always wanted to go and experience it myself. I’m glad I did, as there are views and vistas that had me saying”wow” out loud. I’m not kidding. After only allowing for an afternoon’s visit, I was kicking myself for not allowing the whole weekend to explore. It’s that good.

On the way to the Slim Buttes, I stopped off in the Hoover, SD area to shoot the South Fork of the Moreau River. I grew up near the Moreau River proper around 90 miles to the east of Hoover so this landscape of cut banks, cottonwoods and cattle made me feel like I was home again. After spending the night in Isabel, I made an early morning stop at Little Moreau Recreation Area south of Timber Lake. This relatively wide and scenic creek valley in the middle of the prairie is thick with trees. I had never witnessed what it looked like in the fall before this year. The early morning view was not a disappointment. I had arrived a few days before prime colors, but the scene was still impressive. As a photographer, I’d rather catch fall early than late as the remaining greens can contrast nicely with the autumn’s yellow, oranges and reds.

My last stop was the Foster Bay Road of extreme northwest Stanley County. Here the draws were in full autumn splendor. I found bright reds in the thickets and rich oranges and yellows along the hillsides. I spent a good hour, just taking it all in. A lot of miles lay behind me, but viewing these last bursts of color before the dull and muted hues of winter arrive was truly a blessing. Yes, fall is fleeting in our great state, which means catching it even for just for a moment is a treasure. It’s a good life lesson, really. Life is fleeting, but there are moments and experiences that stand out in vivid color. Enjoy those moments, take pictures and treasure the views!
