by approximately 1750. By the early 1800s, Euro-Americans were becoming more common in the area and evidence of trade with the Native Americans in horses, firearms, and ornamental items is increasingly evident in the archaeological record. Native American tribes, including the Crow, Cheyenne, Sioux, and Arapaho, lost their lands with the Fort Laramie Treaty of 1868, and many were relocated to reservations outside Wyoming.

As is the case with much of the West, the early Euro-American exploration of the Laramie Plains owes much of its beginnings to the fur-trapping trade. In 1820, Jacques Laramie trapped along the river that now bears his name. Although thousands of Euro-Americans traveled through what is now the State of Wyoming in the 1840s and 1850s, most were heading farther west on the nearby Oregon, California, Overland, and Mormon trails, and few of them settled in what would become Wyoming. From 1862 to 1868, approximately 20,000 people per year traveled along the Overland Trail, which ran approximately 3 miles north of what is now Hutton Lake
