About this map

Triangle sits at the base of the high desert uplands in Owyhee County, where local ranching and water management define the landscape. This 2023 survey details a network of vital water sources including Triangle Reservoir and White Horse Reservoir, along with numerous named springs like Stagecoach Spring and Buckroo Spring that have long sustained livestock in this arid environment. The terrain is characterized by the prominent Antelope Ridge and the broad Cow Valley, which provide a natural drainage system for the North Fork Castle Creek and Cow Valley Creek.

Remote roads such as Triangle Rd and Antelope Ridge Rd provide the primary access through this high-altitude cattle country. The map highlights the intersection of natural topography and land use, from the heights of Toy Mtn down to the seasonal flows in Buck Gulch and West Spring Gulch. This modern record preserves the current state of water infrastructure and named natural landmarks essential to the local identity.
