Orr Ranch stands as a primary point of human settlement in this high-altitude basin, where the landscape is defined by a dense network of alpine lakes and mountain peaks. The hydrology of the area is complex, with Antelope Creek and its many tributaries, such as Spring Branch and Poison Creek, draining the slopes of the Horn Mountains and Saddle Mountain.
