Sweetwater County, located in the southwestern part of Wyoming, has a rich and diverse history. The county was initially inhabited by several Native American tribes, including the Shoshone and Ute, who used the area for hunting and gathering. The first recorded European exploration of the region can be traced back to the early 1800s when fur trappers ventured into the area in search of beaver pelts.

In the mid-19th century, the Oregon Trail and the California Gold Rush brought a wave of settlers to Sweetwater County. The county witnessed a significant influx of pioneers as they traveled through the region, establishing trading posts, farms, and small communities along the trail. The establishment of Fort Bridger in the 1840s further contributed to the development of the county as it became a supply center for those traveling west.

The discovery of coal in the 1860s played a crucial role in shaping the future of Sweetwater County. The mining industry grew rapidly, attracting more settlers to the area, and leading to the establishment of towns such as Rock Springs and Green River. The region's coal reserves became one of the county's primary industries and continued to fuel its growth and development throughout the 20th century.

In addition to coal, Sweetwater County has seen the rise of other industries such as oil and natural gas extraction, agriculture, and tourism.
