2017 Map of Rough Mountain

About this map

Rough Mountain dominates this high-desert landscape in Owyhee County, where a series of water sources and passes define the movement through the terrain. The network of seasonal hydrology is evident in the numerous named springs, such as Poison Gulch Spring, Little Half Moon Spring, and Eagle Spring, which likely served as critical landmarks for travelers and ranching operations. The presence of Half Moon Pass and Little Half Moon Pass indicates established routes through the mountainous interior, connecting the drainages of Birch Cr and Poison Cr. While roads like Mud Flat Rd and Missile Base Rd provide modern access, the distribution of names like Vinson Wash and Twentymile Gulch reflects a landscape mapped and navigated by its distinct geological and hydrological features.
