2021 Map of Alkali Creek

About this map

Brown Number 1 Reservoir serves as a critical water management point in this arid stretch of Big Horn County, where the topography is defined by intricate drainages and sharp elevation changes. The land is largely organized around the seasonal flow of Crystal Cr and the prominent Black Gulch, which carve through the high plains. Human activity is focused on a handful of unpaved routes, primarily Crystal Creek Rd, which provide access through the complex network of ridges. This 2021 survey illustrates the continued reliance on sparse water infrastructure and rugged access roads in the remote Wyoming interior, offering a clear view of the landscape's natural drainage patterns and the township divisions of the Public Land Survey System.
