Lake Desmet Segment, Bozeman Trail
The Lake Desmet Segment is a one-mile long set of trail ruts that are a well-preserved portion of
the Bozeman Trail in Johnson County, Wyoming. The ruts are located about a mile west of Lake Desmet on the down slope of the hill overlooking the lake. This portion of the trail is on private property, so permission is required to visit.
==Lake Desmet==
Lake Desmet occupies a natural undrained basin on the divide between Piney Creek, and one of its tributaries, Boxelder Creek. It is one of several basins in the Buffalo area that were formed by coal seam fires. After the coal deposits burned, the clinker and other sediments collapsed into the space vacated by the burned coal forming a natural basin.
In the early years, Lake Desmet was a highly saline lake capable of supporting only limited types of aquatic life. However, during a period of higher precipitation from 1880 to 1915 the salinity of the lake dropped because of additional runoff from local creeks. In 1917, Levi Leiter a Chicago millionaire built an irrigation ditch from Piney Creek to Lake Desmet, and impounded additional water with a small dam. In 1957, Reynolds Mining bought the lake, replaced the ditch with a tunnel and replaced the dam with a higher dam. In 1976, Texaco bought Lake Desmet from Reynolds Mining and they raised the dam again. The original natural lake was about 1500 acres in size, but the various dams have increased the size of the lake to about 3600 acres today.
