OLD SWEETWATER COUNTY JAIL, SOUTH PASS CITY, WYOMING
Located in South Pass City State Historic Site, 2 miles south of the intersection of highways 28 and 131 (35 miles southwest of Lander, Wyoming)
Built in 1870 and used until 1873, today the old structure is considered one of the best examples of an early frontier mining camp jail in the United States. The historic Carissa gold mine is nearby. Open to the public from May 15 to Oct. 1. Note: South Pass City is now part of Fremont County, but was the county seat of Sweetwater County at the time the jail was built (and formerly Carter County).
