2017 Map of Three Creek

About this map

Three Creek serves as a central point in this remote Owyhee County landscape, where the high desert meets a complex system of seasonal drainages and basaltic formations. The terrain is defined by dramatic geological markers such as Black Rock and Castle Rock, which overlook the expansive Beaver Flat and Joiner Flat. This 2017 survey details a network of ranching and access roads, including Three Creek Rd and Elk Mountain Rd, which navigate the winding canyons and draws. Water is the primary sculptor here, with Big Flat Cr and Little Spring Cr feeding into the wider watershed. The southern reach of the map transitions into the Inside Desert, while the eastern portion is dominated by the steep descents of Hays Canyon and the notable Mud Flat area. This document captures the modern state of these high-altitude pastures and the critical water sources that sustain the region's livestock traditions.
