1990 Map of Combination Ridge

About this map

Combination Ridge dominates this Owyhee County landscape, forming a high, north-south divide that separates the drainage basins of several intricate stream systems. The topography is characterized by the convergence of steep canyons, most notably where Big Boulder Creek and North Boulder Creek meet. This 1990 provisional survey records a network of unimproved roads and a Pack Trail that follow the contours of the high desert terrain, suggesting a landscape primarily utilized for ranching or resource management rather than permanent settlement. The intricate web of named watercourses, including Indian Creek and Bogus Creek, highlights the importance of seasonal water in this high-elevation environment. The lack of schools, churches, or cemeteries indicates the remote nature of this portion of the Idaho backcountry during the late twentieth century.
