2011 Map of Roundup Draw

About this map

The northern reaches of Sheridan County are defined by an intricate network of drainage channels along the Wyoming-Montana border. The landscape is carved by numerous namesake features like Tiner David Draw and Horsley Draw, reflecting a topography deeply tied to its water sources and mining potential. Water management in this arid environment is anchored by Antelope Reservoir, which sits at the head of Antelope Draw. The eastern portion of the survey is dominated by the many branches of the Hanging Woman Creek system, including the Middle Prong Hanging Woman Creek and Early Prong West Prong Hanging Woman Creek. Evidence of the region's geological resources is noted at Coal Mine Draw near the Montana line, signaling the industrial importance of the Powder River Basin. The western edge transitions toward the West Prong Waddle Creek drainage, illustrating the complex watershed divide characteristic of this high plains territory.
