2021 Map of Cottonwood Pass

About this map

Cottonwood Pass and Lysite Mtn dominate this high-desert landscape in northern Fremont County, where the terrain transitions toward the southern Bighorn Basin. This survey documents a critical watershed boundary, with the Nowood River flowing north and various drainages like Cottonwood Creek and Snyder Creek cutting through the uplands. The human footprint is defined primarily by historic routes and water sources, including the Bighorn Trl and the Oakie Trl which follow the natural contours of the ridges. Scattered springs such as Brasket Spring, Stove Spring, and the unique Shelly Seeps mark the vital water points essential for life and livestock in this arid environment. The map also delineates the high-altitude county boundaries where Fremont meets Hot Springs and Natrona counties, highlighting the remote nature of this mountain-pass territory.
