2015 Map of Colter Draw

About this map

Thunder Basin National Grassland dominates this high plains landscape in Converse County, where the intricate drainage patterns of the Powder River Basin are clearly defined. The terrain is characterized by numerous ephemeral watercourses and draws, including the primary namesake Colter Draw, alongside the North Fork Crooked Draw and Crooked Draw. These geographical features demonstrate the erosional forces typical of the Wyoming steppe, carving deep into the plateau. Human impact on the land is represented by the Coulter Number 1 Reservoir, a vital water management site in this arid environment. Significant water bodies such as Horse Cr, Willow Cr, and Rat Cr cross the townships, while Walker Creek Rd provides a primary point of access in the southeastern corner of the quadrangle.
