Sego /’se”go”/ is a ghost town in Grand County, Utah, United States. It lies in the narrow, winding Sego Canyon, in the Book Cliffs some 5 miles (8.0 km) north of Thompson Springs. Formerly an important eastern Utah coal mining town, Sego was inhabited about 1910–1955. The town is accessed via the grade of the Ballard & Thompson Railroad, a spur from the Denver and Rio Grande Western built by the founders of the town to transport the coal. Henry Ballard, one of the founders of Thompson Springs, discovered an exposed vein of anthracite coal here in 1908 while exploring the many canyons of the Book Cliffs. He quietly bought the land and began to hire local laborers to mine the coal. The coal camp was naturally called Ballard.


The town’s most serious problem, almost from the beginning, was a diminishing water supply. The water table was dropping, the creeks and springs drying up. One summer the water slowed to such a trickle that the coal washer could not even operate. Paradoxically, the railroad was plagued by excessive water, flash floods frequently damaging the bridges and trestles. The small train that served the mine was off the track as much as one fourth of the time. By 1915 profits were low to nonexistent, and paydays very irregular. Like many mines, the company tried to enforce a system where miners were paid in scrip redeemable only at the company store. Miners who dared to shop in Thompson, where prices were half those at Neslen, were threatened with the loss of their jobs.





Current Status:

The stone company store, boarding house, and many foundations and dugouts still remain. An underground coal seam fire has continued to burn here for decades, and smoke still rises from deserted mine shafts. Another severe flash flood in the early 1980s, known as the “Hundred Years’ Flood” by locals, removed most of the remaining trestles and left the rest unsafe. The wooden boarding house collapsed some time between October 2009 and April 2010.


By 1947 production costs exceeded income, and the company decided to close down. The miners that once had numbered 125 had been reduced to just 27. These remaining miners pooled their resources, and with the backing of two banks bought out the Chesterfield Coal Company assets. Organized under the name Utah Grand Coal Company, the miners hoped to keep the mine operating. Indeed, their first year was very successful. Then fire destroyed the tipple in 1949, and another serious fire the next year burned more equipment. The final blow came when the railroad converted to diesel locomotives, virtually eliminating the demand for coal. The Utah Grand sold its holdings in 1955 to a Texas company that intended to explore for oil and natural gas. Homes were moved to Thompson, Moab, and even Fruita, Colorado, and the schoolhouse was taken to Thompson. Sego was gone. There was a flash flood in the 1950s that wiped out the rest of the miners that still worked there. Not many homes were left standing, and one was partially collapsed from a boulder falling on top of it.
