Sweetwater County Historical Museum

Walk in the Shoes of Early Sweetwater County Settlers 

From the early 1800s through the present day, Sweetwater County has been a bustling area for Southwest Wyoming’s Native Americans, pioneer settlers and mining industrialists. At the Sweetwater County Historical Museum in Green River, you can explore their stories as well as the history of western expansion from the perspective of fur trappers and traders, miners, railroad men and more. 

A Taste of History

The county’s history is well preserved in the museum’s exhibits through timeless photography, original structures and the stories of its people. From Sioux art pieces dating to the turn of the last century to a Sharps buffalo rifle owned by Sheriff W. A. Johnson to the coal mining artifacts from the Union Pacific Coal Company, you will be fascinated by the beautiful and diverse history of Sweetwater County.

Established in 1967, the Sweetwater County Historical Museum is housed in a 1931 post office building in Green River. Listed on the National Register of Historic Places, the museum offers a variety of both permanent and seasonal exhibits.

The museum also lets you peek into the past with a large collection of antique photos that highlight the mining towns of Dines, Winton, E-Plane, Gunn and others in their heyday. A broad display of artifacts reminds us of the immigrants who worked the coal mines and railroads. 

The museum also administers the historic Reliance Tipple, where visitors can take an interpretive walking tour around the tipple and hear coal mining stories.
