Julius Sayles, a Welshman, had a coal mine/cabin according to a 1901 Government Land Office map. In 1902, Sayles filed on 120 acres, but never proved up on it. In 1906, Alfred R. Schultz, U.S. Geological surveyor, surveyed a seam of coal which was 5.5 to 6 feet thick in the Adaville Formation on LaBarge Mountain. It was sub-bituminous coal which had 9,833 BTUs at the mine. Most of the coal was not any good for using in forges. Sayles had a mine entry 180 feet long where he sold coal for $1.50 to $2.00 per ton at the mine. According to a 1910 record, this acreage was subjected to a coal patent. Sayles had a very productive garden with all kinds of vegetables. He liked kids and had wooden gifts for them when they came to the mine. A homestead entry ws applied for in 1914, but was relinquished when Sayles was crushed to death by a rock that fell from the ceiling of his mine. Dave Salmon, a local rancher, came to the mine for coal and found Sayles a few hours after the accident happened. Sayles willed everything to Lawrence Z. Bess. Bess proved up on 80 acres from 1915 through 1920 and acquired the patent. Matt Salli was living at the mine in 1916. Subsequently this mine became known as the Salli Mine. Salli worked the mine with two other Finlanders, Cabe Benice and Oscar Peterson. Salli acquired a warranty deed from Bess for the mine in 1920. Around this time, Matt Salli married Mrs. Sanna Perna Hacklin, a Finnish widow of Victor Hacklin, who was killed in a mine cave-in at Cumberland in 1910 or 1911. Sanna had five children named John, Decia, Mayme, Ila and Velma. Lila Salli was born in 1922. Mrs. Salli had a pet magpie which could talk. She also had a beautiful garden with interesting wooden structures in it. Matt Salli had a Finnish bath which people came to use for 50 cents a bath. Matt was also a very good carpenter and made money with this skill. Mrs. Salli was a good cook, also. When they ran the Twitchell mine, they acquired a piano and Matt could play the accordion so music was popular in the evening. The Wyoming State Coal Mine Inspector inspected this mine from 1932-1936. Matt named his coal mine the Viola Coal Mine. Andrew Kiskila worked in the mine for Matt until he died. In 1932, Matt's post office was Tulsa and he mined 154 tons with one employee while in 1933, he mined 88 tons of coal in 45 days with one employee. One hundred four tons of coal were mined in 1934 with one employee working 20 days. Matt did not report mining coal in 1935, but in 1936, Matt's post office ws LaBarge and he mined 113 tons of coal in 13 days with one man. In 1938, he mined 38 tons and during 1939, he mined 28.5 tons with one employee. Matt Salli died in 1939 or 1940 and the mine closed.

W.J. McGinnis started a coal mine after the McGinnis family's first winter in the area during 1887-88 near what is known today as the Twitchell Mine, just west of Calpet. Mr. McGinnis never sold the coal. He just shared it with his neighbors. After a tunnel was started, McGinnis built an ore cart and carved wheels out of wood for it. The rails were made from aspen trees. McGinnis became so busy with his land that he did not continue the mine.

Oliver M. Twitchell acquired a patent for 80 acres in 1917 and Rose Twitchell, his wife, received a patent for 40 acres in 1919. Rose was a wonderful cook and became known for her great meals she fed the men at the mine whether they were miners or people buying coal. Rose was an extremely hard worker. In the Dec. 6, 1917 Pinedale Roundup, Oliver Twitchell had an ad for coal which was selling for $3.00 per ton. Matt Salli managed the mine in 1926-27. Seven hundred twenty tons of coal were sold in 1927 as well as in 1928 when the mine was worked for 200 days with one employee. The coal sold for $5.00 per ton at the mine, $7.00 per ton delivered to Tulsa, and $10.00 per ton delivered to Big Piney. There was an advertisement in The Kemmerer Republican in 1930 to sell the mine. It said $26,000 worth of coal had been sold in seven years. Gust Manalukos operated the mine in 1930 with one employee and produced 101 tons of coal. Between 1938 and 1940, Oliver Twitchell sold the mine and 80 acres to Dan Shickich and Dan mined 882 tons, but the Wyoming Coal Mine Inspector did not report coal being mined again until 1946 when 1450.5 tons was loaded by hand from what Shickich called the Service Mine. The slope was extended while a new hoist, scale, timber, gravel for the road, tipple, and a large mine fan were purchased in 1947 when 316 lump, 398.5 nut/egg, and 967.5 slack/pea, equaling 1682 tons of coal, was mined by five men. A house was built and scales were put in during 1948 when 2714.5 tons were mined in 215 days. The mine was rockdusted and used permissible powder along with electric cap lamps in 1949 when 2136 tons were mined by nine men in 162 days. There was one fatal accident which was reported in the State Inspector of Coal Mines annual report as follows:

Mary Emeline Twitchell, Oliver's sister, married Joseph D. Batty in Beaver City, Utah on January 23, 1898. They came to the LaBarge area where Batty had a coal mine on the old wagon road which goes up Deloney Canyon at the bottom of Tip Top. In 1906, Norris W. Griggs owned the mine which had an 8-foot thick vein of coal which was in the Adaville Formation. This coal was not very good for forges. The thermal heat unit of the coal at the mine was 9718. Coal was taken out of the 155-foot long mine by ranchers whenever they needed it. The rancher did his own mining and took as much as was needed. An ad in the September 25, 1907 Pinedale Roundup stated O.M. Mitchell again leased N.W. Grigg's coal mine in Dry Piney Basin for five years. It would be open from October 15 to December 20 to sell good clean lump coal for $2.75 per ton. There was a long chute with a new screen. Norris Griggs had several mine claims in the area including gold and copper. He had a ranch where Bill Barney lives in 1997.

John Brady, a deputy sheriff from Kemmerer, had the first coal mine in Snider Basin on Darby Mountain. John Ray acquired the mine from Brady. Ollie Nielson worked for Ray in 1918 or 1919. An Article of Agreement, usually a contract dealing with surface minerals, was filed in August, 1926 between copartners in the Schneider Basin Coal Company. John Ray furnished the coal lease while A.R. Daniels provided one gray mare branded Lazy P Bar on the left shoulder, one bay horse branded Hat L on the left thigh, two bay horses branded Triangle C on the left thigh and KM on the left shoulder, one 3 1/2 inch Bain wagon, two sets of harness, one No. 5 Common Sense bob sled and log chains. Steve Daniels, a nephew of A.R. Daniels, worked at the mine. His pay was one horse along with a gun. Six men worked the mine and hauled coal to the first oil rig at the Narrows. Edwin Shooter mined 200 tons of coal at the Snider Basin Prospect with two men in 1931 while Jack Harlan loaded by hand 18 tons with one employee in 1932. Shorty Kleinstick also ran the mine at one time. During the Depression, Chuck Davis and Paul Virostko worked the mine. Kenny Pearson hauled coal for Chuck Davis. Ollie P. Nielson, who came to the area in 1909 and worked for Oliver Twitchell, opened the mine in 1937. He mined 553.5 tons of coal with one employee. During 1940, Nielson with two men produced 88 tons lump and 60 tons pea/slack which equaled 148 tons of coal from the Kemmerer Formation of the Blind Bull Vein. The coal was hauled to the Budd #1 Well on the Corder Place to thaw it out after it blew. The oil company went broke and in turn, Nielson was not paid so he had to close the mine.

George Edwards had a small mine on Edwards Creek, just above where the creek joins North Piney Creek. Frank Springman, postmaster of Stanley in 1914, recorded this mine to Alfred R. Schultz. The coal is from the Blind Bull Formation. Mrs. Edwards, George's sister-in-law, had a garden with great vegetables and beautiful flowers. She would give away the flowers, carrots, turnips, etc., but the potatoes from the huge garden along the hill were harvested, put into 100 pound sacks, stored in a big underground room with a rope ladder used to descend and ascend, and sold to the local stores for supplementary money. Her two sons, Frank and Red, who were good mechanics, helped her with the garden.

According to the Pinedale Roundup in 1904, Sam Smith and William Alexander, whose ranch is known as the O.M. Winkleman place on Cottonwood today, brought a load of coal in from the Cottonwood mine. In 1906, Sam Smith was operating this 20-foot drift mine which had a 6.2-foot thick vein of coal. The coal is bituminous coal from the Adaville Formation in the McDougal Field. The thermal unit at the mine is 11,999 while the moisture in the coal is 9.6. The volatile matter is 38.71, the fixed carbon is 46.9, the ash level is 4.77 and the sulfur is .32. A road had been built to the mine. A Finlander, Jon Lindstrom, also had a coal mine in this area. Herbert B. "Shorty" Kleinstick, whose post office was Halfway, and Norm Bleamer, whose mother sold their ranch on South Horse Creek in 1928 to Roy Lozier and Phil Birch after his father, W.F. Bleamer, died in 1926, invested the money in the Cottonwood Coal Mine, mined 138 tons of coal with three men in 1932. Kleinstick was still mining at this location in 1935. Kleinstick came to this area from Wisconsin. He was a very ingenious person and could build anything from nothing.
