About this map

Triangle sits at the southwestern edge of this high-altitude landscape, serving as a primary point of reference in a region defined by complex drainage systems and isolated springs. The topography is dominated by the massive Antelope Ridge and the distinct peak of Toy Mtn, with the high meadow of Cow Valley tucked between them. This area represents a critical watershed for Owyhee County, where small drainages like N Fork Castle Cr and Meadow Cr carve through the high plateau.

Water management is evident through features like Triangle Res, alongside numerous vital water sources that likely served early travelers and ranching operations, such as Stageroad Spring, Buckroo Spring, and Antelope Spring. The map captures a network of primitive roads including Antelope Springs Rd and Triangle Rd that follow the natural contours of Seep Gulch and Buck Gulch, providing a detailed look at the rural connectivity of the Idaho interior.
