2013 Map of Combination Ridge

About this map

Combination Ridge and Rose Ridge dominate the landscape of Owyhee County in this 2013 U.S. Geological Survey study, revealing a complex network of high-desert drainage systems. The topography is defined by the deep incisions of Big Boulder Creek and its various tributaries, including N Boulder Cr and S Boulder Cr. These waterways carve through the high elevations, creating a corrugated terrain that dictated the placement of early routes. Two primary corridors, Flint Rd and S Mountain Rd, traverse the high ground, connecting remote parts of the county. The map detail highlights the numerous seasonal and perennial streams like Old Man Cr and Combination Cr that flow away from the central heights toward the Vulcan Gulch area. This survey provides a precise look at the land management boundaries of Townships 6, 7, and 8 South, showing how the natural geography of S Mountain Cr and surrounding peaks intersects with the Public Land Survey System grid.
