2015 Map of Thornton

About this map

Thornton sits at the western edge of the Thunder Basin National Grassland, marking a transition from the drainage of Dumbrill Creek down toward the Green River. The landscape is defined by the management of water in an arid environment, evidenced by the clustered water features near the settlement, including the Thornton Reservoir, Luman Reservoir, and the J W and M J Luman Reservoir. These catchments, along with several draws and creeks like Wind Creek and Patrick Creek, illustrate the historical importance of water rights and livestock support in this section of Wyoming. The terrain rises to notable landmarks such as Shale Hill and Pine Ridge in the south, while the northern reaches are dissected by Tomcat Creek and Willow Tree Springs. This 2015 update shows the county line between Crook and Weston Counties as it cuts across the northern half of the quadrangle.
