Garnet Range dominates this landscape, where the high peaks of Old Baldy Mtn and White Rocks Mtn define a complex drainage system. The terrain transitions from the open Avon Valley in the northeast into a network of drainages including Gallagher Cr and Warm Springs Cr. Historically significant naming conventions are evident in features like Fourth of July Ridge and Cottonwood Meadow, suggesting early seasonal use and navigation markers for ranching or prospecting. The southern portion of the map is accessed via E Brock Creek Rd, tracing the path of Brock Cr through the high country. This modern survey provides a precise look at the elevation and hydrography of the Windy Rock area, documenting the persistence of traditional place names in this remote section of Powell County.
