2017 Map of Big Sulfur Draw

About this map

Big Sulfur Spring and the drainage of Big Sulfur Draw define the central character of this Natrona County landscape. The area is marked by a complex network of ephemeral water sources and seasonal reservoirs crucial for land management, including Alkali Reservoir, Lower Hackett Cr Reservoir, and the uniquely named Suicide Bed Grounds Reservoir. These features, along with the S Fork Powder River in the southeastern corner, illustrate the importance of water infrastructure in the high plains. Movement through this remote territory is traced by historic corridors like Thirtythree Mile Rd and N Willow Creek Rd. The topography is further etched by named coulees such as Stone and Timber Draw and Ellis Draw, providing a detailed look at the drainage patterns feeding into the Lone Bear Cr and its southern fork.
