Sego, Utah

A ghost town to the north of Interstate 70, about 5 miles east of Crescent Junction where US 191 turns south to Moab. Unusually, Sego was the site of a coal(!) mine, long before Colorado Plateau coal became of interest for firing power plants. The area was active in the early-mid 20th century but never prospered, between the marginal deposits and the lack of water. What finally killed the mine (and the town) was when the nearby railroad (Denver & Rio Grande) dieselized in the mid-1950s. The D&RG parallels what is now I-70 and had become basically the only market for the coal, transportation costs being otherwise prohibitive.
This building is by far the most impressive structure still standing and was evidently the company store. The insets show some views from inside the structure. Many buildings were moved when the mine finally shut down, and flash floods over the years have obliterated most of the rest.
