Wyoming is home to the world's largest mineral hot spring, located in Thermopolis. The hot spring is named "The Big Spring" and produces over 3.6 million gallons of mineral water per day. The water is known for its healing properties and is used for therapeutic purposes.
Carbon County, Wyoming is located in the central part of the state and is known for its rich history and natural resources. The area was originally inhabited by Native American tribes, including the Arapaho, Shoshone, and Cheyenne. The first European explorers arrived in the late 18th century, with fur trappers and traders making their way through the region.

In the mid-19th century, the discovery of gold in the Atlantic City-South Pass area brought an influx of prospectors and miners to Carbon County. The county's name itself is derived from the vast coal deposits found in the region, which became a significant economic resource. The Union Pacific Railroad's expansion in the 1860s further spurred development in the county, as it provided a means to transport coal and other resources.

The town of Rawlins, named after Union Pacific Superintendent General John A. Rawlins, became the county seat in 1868. It quickly developed into a center for the region's coal mining industry. Coal production boomed in the late 19th and early 20th centuries, attracting immigrants from various countries to work in the mines. This contributed to the diverse cultural heritage of Carbon County.

In addition to coal, other industries started to develop in Carbon County. Ranching became a vital part of the local economy, as the open plains provided ample grazing land. Additionally, the county's stunning natural landscapes and proximity to outdoor recreational activities, such as hunting and fishing, attracted tourists and outdoor enthusiasts. Today, Carbon County remains an important contributor to the state's energy sector and continues to preserve its unique history and natural resources.
