About this map

Catlow Valley and the prominent ridges of Fish Fin Rim characterize this remote portion of Harney County, Oregon. The landscape is defined by its arid geography, where survival once depended on the scattered water sources and primitive transportation routes that crisscross the high desert. Historically significant routes like the Old Military Rd traverse the northern sections, marking a time when these paths were vital for early interior exploration and military logistics.

Modern water management is evident through a series of specialized features such as East Gulch Waterhole, Three Lakes Waterhole, and Rimrock Waterhole, which provide essential resources in this dry basin. The elevation rises sharply toward Big Fish Fin in the southwest, while the eastern edge is marked by the seasonal expanse of Coyote Lake. This survey provides a clear view of the persistent intersection between human infrastructure and the challenging terrain of the Oregon outback.
