2012 Map of Tule Mountain

About this map

Dogie Mtn and Tule Mtn define this arid Brewster County landscape, where water sources like Gano Springs and Indian Head Spring were historically vital for survival. The terrain is marked by a network of seasonal drainages, including Rough Run and Alamo Cr, which converge near the road junction at Saint Helena Canyon Junction. The presence of Apache Canyon and distinctive landmarks such as The Sphinx highlight the erosion-carved character of the area. This 2012 survey documents the intersection of modern access points like Terlingua Ranch Gate 2 Rd and the more established Castolon Rd, showing how transportation remains tied to the natural corridors between the peaks. Researchers will find a land characterized by its scarcity of permanent water and its sharp topographic relief, including Slickrock Mtn in the north.
