2017 Map of Pinnacle Rocks

About this map

Thunder Basin National Grassland dominates this section of the Wyoming high plains, where the landscape is defined by an intricate network of ephemeral watercourses and subtle topographic rises. The drainage pattern is particularly dense, characterized by named features such as West Fork Rattlesnake Draw and Nachtman Draw which carve through the arid terrain. The Miller Hills and the namesake Pinnacle Rocks provide vertical relief against the wide-open prairie, while the Middle Cr Reservoir serves as a vital water catchment for the region. The map also delineates the jurisdictional boundary between Converse and Niobrara counties, showing the rural infrastructure of Cow Creek Rd and K-Field Rd that connects isolated ranchlands. This document captures the intersection of public land management and the traditional cattle-grazing geography of the American West.
