1990 Map of Triangle Reservoir

About this map

The settlement of Triangle serves as a small anchor for this 1990 survey of Idaho's high desert, characterized by a complex network of springs and seasonal water sources. The landscape is defined by the prominent Antelope Ridge and the broad reach of Cow Valley, where numerous natural water points like Stagecoach Spring and Antelope Spring supported life and livestock. The area's hydrology is further detailed through features such as Triangle Reservoir and the White Horse Reservoir, which manage the flow of creeks like North Fork Castle Creek and Louise Creek. A labyrinth of 4wd routes crisscrosses the terrain, indicating the practical, rugged transit methods required to navigate the gulches and ridges. This map captures the region's ranching and wilderness character, highlighting the critical importance of specific water locations such as Buckaroo Spring and Toy Seep in an arid environment.
