About this map

Big Sulfur Spring and the surrounding drainage systems of Natrona County characterize this high-plains landscape. The area is defined by its complex network of seasonal water sources and draws, including the namesake Big Sulfur Draw and the distinctive Stone and Timber Draw. Water management for livestock and local use is evident through scattered reservoirs such as Alkali Reservoir, Lower Hackett Cr Reservoir, and the curiously named Suicide Bed Grounds Reservoir.

Modern infrastructure is limited to corridors like Thirtythree Mile Rd, leaving the natural hydrology largely undisturbed. The southern reaches of the map include the headwaters and tributaries of the S Fork Powder River and Indian Cr, while the northern section is drained by Hackett Cr and Lone Bear Cr. This survey provides a clear view of the ranching-dependent terrain, where specific named draws and springs serve as critical landmarks in an otherwise open Wyoming territory.
