Rock Springs | USA Wyoming

Rock Springs is an incorporated city in Sweetwater County, situated on the high desert plains of the Bitter Creek valley. Known as the "Home of 56 Nationalities," it is defined by its deep coal mining roots, its extreme ethnic diversity resulting from the Union Pacific Railroad's recruitment of global labor, and its role as a gateway to the high-desert wilderness of Southwest Wyoming.

Historical Timeline

Inhabited by the Shoshone and Ute peoples. A critical historical event occurred in 1885 with the Rock Springs Massacre, a violent labor conflict where white miners killed at least 28 Chinese miners and burned their homes; federal troops remained in the city until 1898 to maintain order. Founded in 1862 as a stage stop and formally incorporated in 1888 following the arrival of the Union Pacific Railroad. The city’s history is inextricably linked to the extraction of coal, which powered the transcontinental rail line. In 2026, the city remains a critical industrial hub for Trona mining (soda ash), oil, and natural gas.

Demographics & Population

The 2026 population is approximately 22,950. The demographics are White (80%), Hispanic or Latino (17%), and Two or more races (10%). The economy is driven by Mining and Extraction (Sweetwater County contains the world's largest trona deposit), Energy, Transportation, and Education (Western Wyoming Community College).

Facts & Legends

Rock Springs is where the outlaw Butch Cassidy earned his nickname while working at a local butcher shop (Robert LeRoy Parker became "Butch"). Historically, the city was the only place in the U.S. where the "International Day" festival originated to celebrate 56 different immigrant groups simultaneously. A local legend involves the "Underground Chinatown," rumored tunnels beneath the modern streets where survivors of the 1885 massacre allegedly sought refuge and lived in secrecy. Another legend concerns "Boar's Tusk," a 120-meter volcanic spire north of town said to be a spiritual focal point that causes compasses to fail.
