About this map

Combination Ridge and Rose Ridge dominate this high-elevation corner of Owyhee County, where a complex network of drainages defines the landscape. The hydrology is particularly intricate here, as headwaters like South Mountain Creek, Coyote Creek, and Indian Creek carve deep into the terrain. Most of the area remains largely undeveloped, with Flint Rd in the northeast corner serving as one of the few primary access points into this remote high-desert environment.

Water movement is the primary characteristic of the topography, with multiple forks including Big Boulder Creek, North Boulder Creek, and South Boulder Creek converging in a series of steep canyons. The drainage pattern, including Combination Creek and Mill Creek, suggests a landscape shaped by seasonal runoff and significant elevation changes, typical of the Owyhee range. This survey provides a precise account of these natural features within the Public Land Survey System townships of T7S R4W and T8S R4W.
