SD-000.0 N. Dakota/S. Dakota Line

SD-001.5 White Butte
(85 pop.), the last town in South Dakota on US 12, is a typical Western movie village, its few houses evidently built without much idea of the town’s coherence. Since it is a railroad town with a favorable location as a stock shipping point, it is a familiar sight to see cows or sheep dodging behind houses as the herds are driven to the stockyards for their long journey to market. WPA-SD*

A village; rooms; small garage; free camp space. C. A. SAMPSON’S GARAGE leads; has good name and good mechanics. Labor $1.25; ph. 15 until 11 p. m. MH-1928*

NOTE:  Before US 12 was given its modern alignment the highway ran directly north of White Butte, on a now abandoned road.

White Butte is the first town in South Dakota going east and the last going west on the Yellowstone Trail (now US 12). It was founded in 1909 and named after the white limestone butte nearby.

In Yellowstone Trail days it was a stock shipping point with many businesses to support the ranches in the area. When the Milwaukee Road railroad left, White Butte shrank, like many other small towns abandoned by railroads.

SD-012.7 Lemmon
(2,567 alt., 1,785 pop.), was named for “Ed” Lemmon, pioneer and cattleman who for years was foreman of the large L7 cattle outfit. The town is the trade center for a large territory in both North and South Dakota, which produces grain, cattle, horses, and sheep. Thus, it is one of the few towns in the United States where cattlemen, sheepmen and farmers meet on a common ground. Situated on the North Dakota Line, part of the town is actually in the adjoining State.
Attempts at farming in the immediate vicinity have resulted in much distress during recent drought years, although the soil is exceptionally fertile. WPA-SD*

pop. 1,300;YELLOWSTONE HOTEL is now best; 4 rooms with r. w. All rooms to be made modern; sgl. $1.25; dbl. $2.
LEMMON AUTO CO. Ford, large and modern; has best mechanics for all cars. Open to 10 p.m. labor $1-$1.25; ph. 29 for tow car. MH-1928*

When you get to Lemmon you know you are on the prairie – the Great Plains. Windswept and glorious in the sunlight, one can just imagine the early explorers and wagon trains lumbering slowly, pushing our nation west. Lemmon is near Grand River National Grassland and Cedar River National Grassland and the area is characterized by rolling hills dominated by mixed grass prairie with scattered outcrops of badlands.

“Lemmon and surrounding area offers a way of life you can’t find anywhere else. It is the way of life of the Northern Plains, of the prairie and of the Yellowstone Trail.” Highway 12 Guide 2005.

Lemmon figured large in the story of the Yellowstone Trail. Oct. 9-10, 1912 Good Roads folks invited the Ipswich founding group to Lemmon to form an association. It was here that ByLaws were written and the long moniker of “Twin Cities-Aberdeen-Yellowstone Park Trail” was hung on their invention. It would be shortened to “Yellowstone Trail” later. Lemmon would remain a faithful contributor to the Association for its entire 18 year run.

It is also the starting point of a cross-state run in a Studebaker Six in May of 1915 by Trail founder Joe Parmley. His run ended at Big Stone City, 349 South Dakota miles, 800 pounds of South Dakota mud and 16 hours later. See Trail Tale: Parmley’s Trip, page <?>.

On US 12 (Yellowstone Trail) the Grand River Museum displays an interesting mix of local homesteaders’ lives along with geological and paleontological artifacts such as dinosaur bones of T-Rex Sue and a triceratops. Depictions of Native American culture, cattle branding and Lewis and Clark’s trek all bear credibility because of the proximity of those events to Lemmon. An interesting statue of a triceratops stands outside of the museum. It is made entirely of scrap metal!

On Main St. is the amazing world’s largest Petrified Wood Park and Museum. It covers a whole city block, is outdoors and is free. You probably have not ever seen so much petrified wood in one spot before. It looks like the TV town of Bedrock with Fred Flinstone popping up among these “rocks”. There is a 300 ton castle with turrets, also round balls, monuments with Yellowstone Trail printed on them, and cones tall and small. All man-made. Look closely and you will find dinosaur tracks and fossils. The “castle,” built entirely of petrified logs, contains the gift shop where you can buy – what else? petrified wood bits.

SD-021.6 Thunder Hawk
(100 pop.), has a general store where on Saturdays commodities, politics, and gossip are exchanged over the cracker and pickle barrels. WPA-SD*

Thunder Hawk is on the western edge of the Standing Rock Reservation.

The STANDING ROCK INDIAN RESERVATION, covers the eastern half of Corson Co. in South Dakota, and extends into North Dakota, with the Agency at Fort Yates, N. Dak.

There are 3,828 Sioux Indians on the reservation roll, 2,565 of which are listed as full-bloods by the agency superintendent. The native bands within the Sioux Tribe on this reservation are: Hunkpapas, Yanktonai, Teton, Minneconjou, Itazibeo, Oohenupa, Sihasapa, Ogalala, Sicungu, and Isanyati. The native language is used by 90 percent of the people over 40, and by half the children of pre-school age, little by school children. Rodeos are held at irregular intervals during the summer months. WPA-SD*

SD-029.9 Keldron

SD-033.9 Morristown
(2,240 alt.,.235 pop.), named for the C-7 ranch proprietor, Nels Morris. It supplies the surrounding ranchers with such supplies as they do not get from mail order houses.
A village in a wheat and flax growing district; three garages. Stadel Garage leads. No camp. MH-1928*

SD-044.6 Watauga
pop. 100; wheat, flax and barley are the principal crops. Fair country hotel. Simon-Thompsen Garage is best. Open camp space. MH-1928*

Watauga, Corson County, is located 10 miles west of McIntosh, the county seat. It is on the main line of the Chicago, Milwaukee, and St. Paul Railway and on the transcontinental highway, the Yellowstone Trail. The community surrounding this prosperous village is noted for its mammoth growth of prairie grass, affording pasture and hay for thousands of stock, and with rich deposits of Lignite coal which can be purchased at from $1.00 to $2.00 per ton. The community has RFD, telephone lines, and radio receiving sets. Excerpted from Watauga Commercial Club publication 1923.

On the corner of 2nd Ave. E and US 12, the northwest corner, you will see another small “hoodoo” painted yellow with black vertical lettering of the Yellowstone Trail. It is across 2nd Ave. from Brenda’s Tumbleweed Café at 22870 US 12.
Four miles east of Wautaga on the north side of the road about 20 feet from the road is a bullet-shaped hoodoo Yellowstone Trail marker painted white with a yellow stripe.

SD-054.0 McIntosh
Between Mcintosh and Lemmon the rolling country breaks into occasional sharp buttes and grassless mud flats. This land was once the paradise of cattlemen; it still is, but in a different sense. The cattleman must rent his land today; yesterday it belonged to anyone or no one. Here, where there are few towns and the roads are impassable in wet seasons, the temptation to go to town is less. Men and women are wind-burned the year around, and children are virtually raised in the saddle. WPA-SD*

Wheat and sheep raising are the main sources of revenue. Boots Cafe is best. H. & C. Motors is reputed good. Mcintosh Motor Co., for Fords. Free camp space, cold showers. MH-1928*

There was a Trail Garage there in 1924.

Native Americans of Standing Rock Reservation put on shows for tourists in Yellowstone Trail days.

McIntosh is the county seat of Corson County which contains much of the Standing Rock Reservation. Present county officers were much interested in the Yellowstone Trail. Sadly the offices burned down, preventing further research there. The Reservation also straddles the border into Sioux County, North Dakota. Lakota Sioux Indians populate the South Dakota portion. It is the sixth-largest reservation in land area in the United States with a land area of 3,571.9 square miles. McIntosh was laid out and parcels sold in 1910 by the Milwaukee Land Company, a division of the Chicago, Milwaukee, St. Paul and Pacific (The Milwaukee Road) Railway.

McIntosh, as a boom town, marched to the rhythm of the railroad: pool halls and cafes never closed. In 1912 there was [sic] six stalls for engines in the yard and six being built. Three hundred houses stood south of the railroad track where railroad workers lived. Many houses in town with a spare room had a boarder. When the First World War came, three shifts went on in the yards. In the thirties people were forced to turn to the railroad for coal – bits stolen, mostly. Stock was shipped out of the country by rail for decades. The railroads have changed now. High speed steel and diesel trains carry big loads across country without a stop. Morristown World June 1958.

SD-088.4 McLaughlin
Is the center of Standing Rock Indian Reservation which is the home of 5,000 Sioux Indians. Indian tent village 10 miles south on river; visitors permitted. This is one of the largest tractor farming areas in the west; wheat and flax farms as large as 2,000 to 5,000 acres are found between here and Mcintosh. Eat at Dew Drop Inn; best and clean rooms at Mrs.Wehrfritz, $1 a person. Free camp on hill only fair. JEWETT GARAGE has good name; open 24 hrs.; labor $1;phone 12 for road service. MH-1928*

(1,633 alt., 200 pop.), is a settlement of whites and Indians. The one-street village, of frame buildings and a bright new community hall, has board sidewalks. A modern, brick schoolhouse contrasts with log cabins and tents in the wooded outskirts of the village. WPA-SD*

Routing the Trail through Corson County was always a problem for the Yellowstone Trail Association, almost the whole of the county being on the Standing Rock Reservation. In 1916 Joe Parmley and others laid out a route. Before that the Trail ran along unimproved prairie trails. As late as 1938, US 12/Corson County boosters were begging for oiling their road, evidence that the Trail was still not much improved.

Traveling from the west, the land gently descends from the uplands as the road enters the Missouri River valley. Trees are scarce, visible only lining the length of creeks or planted in yards.

312 Main St., three blocks south of US 12 (Yellowstone Trail). Major James McLaughlin Heritage Center. You could stop to see if this interesting, little museum is open. It might not be. The Center was named for James McLaughlin, Indian Agent for the Standing Rock Reservation in the late 1800s. The small Center features a Major James McLaughlin family display and historical documents, early local settlers’ memorabilia and hand made Indian articles and art.

The route east of Walker is gravel and not recommended when wet. There are no gas stations or other services in this area other than in McLaughlin. The eastern part of 102 St. is little used with minimum maintenance. 257 Ave. is also Co. 13-2. 101 St. is also Co. 2. 260 Ave. is a narrow lane and an “authentic experience.” Old SD 12 is made of packed clay.

SD-119.1 Wakpala
Wakpala is on the Native American Scenic Byway which runs from the northernmost North Dakota point of the Standing Rock Reservation past Fort Yates, North Dakota, and south through Corson County, South Dakota highway 1806 and south for 90 miles. Most of the Byway is on Native American reservation land. Thus, the present Byway followed about 18 miles of the early route of the Yellowstone Trail in eastern Corson County.

WAYSIDE – Travel south from Wakpala on Co. 1806, the Lewis and Clark Highway, for about 12 scenic miles and you will come to the Sitting Bull Grave Site, and a little further, the Sakagawea (Sakakawea) Monument. Or you can get there from Mobridge by going six miles west of Mobridge on U.S. 12 and four miles south on 1806. This is the final resting place of the great Sioux warrior.

Sitting Bull is mostly remembered today as a brave and wise leading figure in battles against whites, in the Battle of the Little Bighorn in which Custer died, and as a leader of the Hunkpapa Sioux. He is also remembered as part of the famous Buffalo Bill Cody’s Wild West Show. He was killed in 1890 on the Standing Rock Reservation on which stands this memorial. He was buried at Fort Yates, North Dakota. Sixty-three years passed. The grave at Fort Yates had been neglected and poorly marked. With permission of his relatives, a delegation of men from Mobridge Chamber of Commerce quietly arrived at Fort Yates in April, 1953, and disinterred the bones. He now rests in a steel vault with 20 tons of concrete on top of it on a bluff overlooking the Missouri River/Lake Oahe. Sculptor Korczak Ziolkowski, who began the Crazy Horse Mountain carving near Mount Rushmore, agreed to sculpt the bust of Sitting Bull. GPS: 45.51696, -100.48521.

Variously spelled Sacagawea, Sakakawea. and apparently 15 other ways, not one with a “j”, is a memorial to Lewis and Clark’s Indian guide. Controversy still whirls around her life story. Her birth date of 1787 meets with less controversy than the date and place of her death and burial.

Tribute is paid to “Bird Woman” with this monument which is a few miles away from the Missouri River site where Lewis and Clark once camped. Oddly, the memorial looks more like the Washington monument obelisk in Washington D.C. than a Native American design.
GPS: 45.51588 -100.48811.

SD-129.5 Mobridge
As the division headquarters for the Pacific extension of the Milwaukee Railroad, the town grew rapidly. A large railroad yard still remains. An excellent collection of Indian relics taken from Ankara village sites near Mobridge is displayed on Main St. In Mobridge are seen ranchers with ten-gallon hats and cowboy boots, and Indians in overalls or shawls. WPA-SD*

At Yellowstone Trail and Main St.; pop. 3,000; the live trade center for a big territory, also an important freight and passenger division. Best meals at Pierce Cafe, lunch 40c. City camp, 25c.
BROWN PALACE HOTEL all rooms outside, light and with toilet; dbl. $2.75-$3; with bath $3.75-$4. Cafe in conn.
PIERCE HOTEL is second best; 29 rooms with r. w. and steam heat, 2 with bath; sgl. $1.25; dbl. $2; with bath $3.
S. ERDAHL in Buick Garage on Trail, is reputed best mechanics; labor $1.25; emergency night work; ph. 410 for 24 hr. road service.
DARLING AUTO CO., Ford, is large and modern. Phone 440 until 10 p. m. MH-1928*

There was a Yellowstone Garage in 1924.

In May of 1906 work began on the railroad bridge which was to become “the mightiest bridge built anywhere across the Missouri” according to the 1981 Mobridge Tribune 75th Anniversary Special Diamond Jubilee Section. There was no town until the railroad company established one three miles south of the bridge. They used the railroad telegrapher’s abbreviation for Mo. bridge as the name of the new town. It became a major division headquarters with a 26-stall roundhouse. Like other railroad towns, folks moved to the rhythm of the railroad, its major employer. The bridge was replaced over the wider Lake Oahe, created in 1962 now spanning 2349 feet of water.

Mobridge (Bridge City) is surrounded on three sides by Lake Oahe which was created in 1962 by a Dam on the Missouri River near Pierre. The lake swallowed the much narrower Missouri River. Thus, today one sees huge bays and sweeping bridges and a small town making the most of its watery kingdom by attracting tourists and fishermen to this “Walleye Capital.” As you look at maps in this book and read about ferry boats and a 1924 auto bridge at Mobridge, you must remember that the distance a bridge had to cover before 1924 was about 1800 feet, not the vast expanse of Lake Oahe created in 1962. For a discussion of Mobridge’s ferry boats, the 1924 bridge, and the Yellowstone Trail, see Trail Tale: Missouri River, page <?>. See also the map on page <?>.

Even today people in Mobridge and area are aware of the Yellowstone Trail. There is an area school athletic conference called the Yellowstone Trail Conference, a ranching association called Yellowstone Trail Livestock Improvement Association and even a quilting group called Yellowstone Trail Quilters. Into the 1970s there was still a Trail Café and a Yellowstone Trail pheasant farm. A Yellowstone Trail Café again appeared in the early 2000s.

1820 W Grand Crossing (west US 12; the Yellowstone Trail). Klein Museum. European and Indian cultures are both on display in western antiques and in Sioux and Arikara Indian artifacts and beadwork. Typical early scenes such as a post office, dentist’s office, and railroad memorabilia are displayed. Living history tours provide hands-on events for children.
212 Main St. The Mobridge Auditorium (Howe Arena). Ten murals, 16’ tall X 20’ wide, depicting Sioux Indian ceremonies and history decorate the interior walls. Voice narratives accompany viewing. All were painted by the late Oscar Howe, world renowned artist and South Dakota Native American. The auditorium is on the National Register of Historic Places.
301 N Main St. The Brown Palace Hotel. Now called the Brown Palace Apartments. Opened in 1918 by A. H. Brown who said, “The people of Mobridge would have a beautiful hotel, as well as public restrooms on Main Street.” It took around three years to complete the three-story 110-room building. It also contained a barbershop, lunch room, dining room, and eight apartments. Today, the hotel’s exterior appearance remains much the same as in 1918. This building represents an important piece of Mobridge’s history.

WAYSIDE – A walking trail along the shores of Lake Oahe is located just south of town.
River bluffs and rugged buttes to the west across Lake Oahe, and rolling plains to the east seem to protect Mobridge down at lake level. One can imagine buffalo by the thousands on the prairie grasslands. One can imagine Mobridge as the big cattle shipping site which it once was. A packing plant was needed, but people objected to the possible smell. “People all came from small farms. It’s funny how that smell is bad when you move to Main St.,” said resident Mrs. Dale Shillingstad.

SD-150.7 Selby
Cattle and horse raising is carried on extensively as well as farming.
Although Selby is several miles from the Missouri River, nearly every spring one resident builds a houseboat, pulls it to the river, floats down to New Orleans for the winter, sells his boat and returns to build another. WPA-SD*

The crest of the Missouri River breaks is reached in the area, with a view of the river and bottom-land stretching N. and S., fringed with cedar, willow, and cottonwood trees. Here farming and livestock-raising are carried on together, and proposals for large irrigation projects are made annually. WPA-SD*

pop. 800; a wheat area; many German inhabitants. Free camp space on Trail.
HOTEL AUBURN is clean. Dbl. $2; meals 50c. MANKE AND TAYLOR GARAGE, is best equipped; owner a fine mechanic. Labor $1.20; open late. MH-1928*

This is the county seat of Walworth County. It wasn’t easy, though. Bangor had been the county seat for 20 years, but Selby won a Circuit Court judgement and was the county seat briefly. After several differing court judgements, Selby finally won and a court house was built there in 1913.
4304 4th Ave. County Court House. Go take a look at the 100 year old building which looks like a midwestern court house should. Built about the time the Yellowstone Trail reached Selby.

One hundred years ago travelers on the Yellowstone Trail may have camped overnight at the Selby City Park. It’s still free today.

Corner of Scranton and Main Sts. (SD 103/Yellowstone Trail) Chesky Auto Co. You can’t miss it. The name is prominently displayed over the entry. In 1917 a frame garage was erected on the site, called the Yellowstone Garage. In 1925 Wm. G. Chesky bought it and by 1928 it became Chesky Garage in the brick building that you see. Today it is used only for storage.
3409 Main St. Selby Opera House. Built at $12,000 in 1908. Traveling theater companies put on plays, movies were shown, the Commercial Club was formed there and today, at over 100 years, it is still going strong.

SD-158.4 Java
pop. 330; grain and stock are chief support; country hotel. Spiry & Sons Garage is good Ford agency.
MH-1928*

The little town had an intriguing name. Story has it that it was named for a really good cup of coffee at a track-side shack for railroad crews. The town was a railroad town settled by people of German and Russian descent in 1900 and got its streets graveled in 1925 in a novel way: money was transferred out of the “liquor fund” on a monthly basis and utilized for the betterment of the streets and walks.

No doubt one of those streets was Main Street, the Yellowstone Trail.

The “stair step” route of the Yellowstone Trail that you see south of Java on the map is a good example of the way roads were routed in the early 1900s. Farm section lines determined the route.
By 2000 most of the buildings were dismantled and folks had moved away, allowing time for prairie grass to begin to return, crowding over the once-bustling town.

SD-173.4 Bowdle
pop. 900; mostly German; rooms but no hotel; Bowdle Sales Co. Garage leads. Good meals at Carlsons. Free camp with cook house. MH-1928*

There was a Yellowstone Trail Garage in 1924.
Bowdle was settled by farmers of German and Russian heritage and named for Alex Bowdle, a townsite agent for the Milwaukee Road railway. Bowdle became a large grain milling and shipping center because that was the terminus of the railway. Like its neighbors, Bowdle had a municipal light plant in 1911 giving unreliable and limited service until 1925 when the Northern States Power Company stabilized the utility.

NOTE – Near Java, as elsewhere, the first route of the YT followed the least muddy section line right-of-way. Some became good roads, others became farmers’ fields. Several combinations of section lines were used here, apparently.

NOTE – The YT route just north and west of Selby is now gravel, perhaps poor. A Clason SD map of the period indicates that the route north of Selby ran one mile east of and parallel to 370 Ave.(From “Clason on disk”).

SD-189.0 Roscoe
(1,826 alt., 540 pop.), is a trade center for a farming community, not unlike the small towns of the movies, with pool halls, tall red grain elevators, general stores, square houses, and large frame churches.
WPA-SD*

The Homestead Act of 1862 drew many immigrants to the promised 160 acres of land at $1.25 per acre. There were farms, but no surveyed town until 1883.
Roscoe was the first home of Joe Parmley, founder of the Yellowstone Trail. He arrived from Wisconsin in April, 1883, having walked the 40 miles from the railroad end in Aberdeen. Upon his arrival, he joined fellow tenters (there was no town there) Sam Basford and Chas Morgan. The three named the “town” Roscoe after Morgan’s father’s friend, U.S. Senator Roscoe Conkling of New York. Parmley and Henry Huck established a newspaper, the Roscoe Herald, on Huck’s printing press. Parmley moved his house (literally, with horses and rollers) to Ipswich when the train arrived there in 1885. He continued to publish the paper until 1910 when it became the Ipswich Tribune after Parmley had moved to that city. For more on Parmley’s life and the Yellowstone Trail, see Trail Tale: Parmley, page <?>.

SD-195.5 Beebe
Marcus P. Beebe founded the town and was its first banker. He was a friend of Joe Parmley of Ipswich and was a “founding father” of the Yellowstone Trail Association in 1912, and served as its interim president to February 1913 when a first election was held.
The Milwaukee Road railroad arrived in 1886 and served the community until 1982. Once a thriving town with hotels, a post office, churches, and schools, the town of Beebe served as a protection for people traveling the Yellowstone Trail in the winter blizzards. Today there isn’t much left of Beebe to see as folks started to move away in 1942.

SD-204 Ipswich
The promotion of the Yellowstone Trail (US 12) from “Plymouth Rock to Puget Sound” was begun at Ipswich by Joseph W. Parmley, and the organization, now known as the U. S. No. 12 Association, still maintains its national headquarters here. A World War memorial arch spans the highway, bearing the name of the Yellowstone Trail and its founder. WPA-SD*

pop. 943; a grain and stock raising center. The St. James Hotel is not modern, but best. Yellowstone Garage reputed good. Motor Sales Co. is open late. Camp 35c at serv. sta. on highway. WPA-SD*

Ipswich is known as the “Home of the Yellowstone Trail” because it was there that resident Joe Parmley founded the Yellowstone Trail Association. Parts of the Yellowstone Trail in Ipswich (8th St. to Broadway) finally got paved with concrete in 1937, but the town itself still has side streets of gravel.

During the summer of 1883 the Chicago, Milwaukee, and St. Paul Railroad built 26 miles west of Aberdeen and stopped. The name of the stopping point was selected by a Milwaukee Road official who was from Ipswich, England. Thirty years later Ipswich was “one of the important shipping points on the Milwaukee Road.”

If you visit Ipswich in June you may have the luck of viewing their “Trail Days” a weekend of celebrating the Yellowstone Trail which they have had, on and off, for the last 100 years. Parades, pie contests, bull riding (real bulls), and much more.

319 Fourth St. J. W. Parmley Historical Home and Museum. It is on the National Register of Historical Places. The museum was the original home of J. W. Parmley, built in 1919. The home is built of cement, brick and plaster, thought to withstand the many prairie fires that occurred during the early days of Ipswich. Parmley had suffered a house lost to fire before. Active in the Anti-Saloon League, Parmley suffered the loss of his house to a suspected pro-saloon arsonist. There are even a cement bath tub and cement floors. There are two stone fireplaces, which include stones and fossils from all over the world, collected by Parmley during his extensive travels.
115 Main St. The Parmley Land Office Museum. Joe Parmley was a land and abstract agent. He sold land to settlers, knew much about agriculture and was a “dreamer” in that he saw and worked for projects to better people’s lives. His land office is in a 1900 stone block building. It offers a large map of the entire Yellowstone Trail, views of early Ipswich businesses, and yet another fireplace built of interesting memorabilia and rocks. For a more full story of Parmley’s life, see Trail Tale: Parmley, page <?>.

Between 8th and 9th streets along US 12, the Yellowstone Trail, there is a memorial arch standing in Collier Park. That arch has quite a history and is worth seeing.
120 Main St. Marcus P. Beebe Memorial Library. Beebe was a banker, philanthropist, and early Trail Association booster.Two other buildings of note are the Marcus Beebe home across the street from the Parmley Home Museum and the First Baptist Church. They are all built of fine fieldstone of the Dakota Territory. The library has a Medicine or Prayer Rock in its front lawn. Found in Mobridge, this petroglyph on a glacial boulder contains the hand prints of a Native American and was considered a symbol of great power.
