Wyoming is the only state in the United States that has an official state dinosaur. The state dinosaur is the Triceratops, which roamed the area during the Late Cretaceous period.
Sublette County, located in the state of Wyoming, has a rich and diverse history that dates back thousands of years. The region was originally home to various Native American tribes, including the Arapaho, Shoshone, and Crow, who relied on the abundant natural resources for their survival. The first European explorers arrived in the area in the early 1800s, with trappers and fur traders venturing into the region in search of beaver pelts and establishing trading posts.

In the mid-1800s, the Oregon Trail brought even more settlers to Sublette County as they traveled westward in search of better opportunities. These pioneers established ranches and farms, taking advantage of the fertile soil and favorable climate for agriculture. The discovery of gold in nearby South Pass further fueled the region's growth, attracting prospectors in hopes of striking it rich.

By the late 1800s, the expansion of the railroad network had a transformative effect on Sublette County. The Union Pacific Railroad reached the region, opening up new avenues for trade and commerce. This led to the establishment of towns and the growth of industries such as timber, mining, and ranching. Sublette County became known for its vast grazing lands, attracting cattle ranchers from across the country.

In the 20th century, Sublette County continued to thrive as an agricultural and natural resource-based economy. The development of oil and gas fields in the area brought additional economic prosperity, and with it came new challenges and opportunities. Today, Sublette County is a mix of historic traditions and modern industries, with a strong focus on outdoor recreation, tourism, and energy production.
