About this map

Fish Fin Rim and the prominent Big Fish Fin anchor this high desert landscape within Catlow Valley. The region is defined by its water management for livestock, with a network of scattered resources including East Gulch Waterhole, Rimrock Waterhole, and Beach Top Waterhole providing essential points in the arid terrain. These features, along with several Wells and the Three Lakes Waterhole, illustrate the infrastructure required for ranching in Harney County during the early 1970s.

A Jeep Trail provides the primary means of navigation through the depressions and gaps, such as Coyote Gap, leading toward Coyote Lake in the southeast corner. The presence of the Mustang Jail near the southern boundary suggests the localized history of wild horse management or containment in this specific corridor of the Oregon desert. The map captures a high-elevation environment where natural depressions and rimrock formations dictate the movement of both animals and people.
