2011 Map of Pentecost Reservoir

About this map

Haystack Butte dominates the northern horizon of this landscape, where the seasonal drainage systems of Powder River County define the local geography. The map reveals a network of canyons and draws, such as Cedar Canyon, Kuster Canyon, and Quaking Aspen Draw, which channel runoff toward Crow Creek. This area's ranching and land-management history is reflected in the sparse infrastructure, primarily consisting of unpaved routes like Jim's Rd and Crow Creek Rd. At the southern end of the sheet, Pentecost Reservoir serves as a critical water source in an otherwise arid terrain characterized by features like Moody Draw and Reynolds Draw. The naming of local landmarks, including Hay Draw and Pentecost Draw, suggests a history tied to early homesteading and livestock grazing in the Montana plains.
