Uinta County (pop. 21,118), in the state’s southwestern corner, is Wyoming’s second-smallest county in square miles.
The county is named for the Uinta Mountains, which are visible across the Utah state line to the south.
The county seat is Evanston (pop. 12,359). Its population grew from about 6,000 in 1980, thanks to the oil and natural gas in the region.
Evanston has the oldest courthouse in the state. It was built in 1873-74 and expanded in 1910.
The Union Pacific roundhouse (1912-13) and other historic structures are still standing in the Union Pacific Railroad Complex in Evanston.
The Wyoming State Hospital (formerly the Wyoming State Insane Asylum) is in Evanston.
Bear River State Park is just east of Evanston. The 491-mile Bear River is the largest river that flows into the Great Salt Lake.
Farther east on Interstate 80 is Fort Bridger State Historic Site. It was a 19th-century fur trading post, supply point for wagon trains, and military post.
