Also on display is the Colt revolver used by 1878 Sweetwater County Sheriff William Johnson and various early law enforcement badges. The most significant event in Sweetwater County s history was probably the arrival of the Union Pacific Railroad in 1868. The company built a repair facility at Green River and operated coal mines in many county locations including Rock Springs, Superior, and Reliance. The railroad exhibit includes a locomotive number plate, lanterns, and a china set used on the last passenger train that came through Green River. Also included are telegraph keys and an insulator used on the first intercontinental telegraph line in the 1860s.
Exhibit tells the story of the most difficult car race in history.
Three cars from France, one from Germany, one from Italy and one from the United States entered the race. The race was to start in the middle of winter and head westward across the United States. In 1908, no one had crossed the United States in an automobile in the winter. The cars came through Rock Springs and Green River on their way to Paris. The Aviation Exhibit includes the 1919 air race, air mail and Amelia Earhart s visit to Rock Springs.
