About this map

Del Norte Mountains define the central axis of this landscape in Brewster County, where the high desert terrain transitions into steep peaks and narrow passages. The topographic detail highlights Rock House Gap, a notable break in the mountain range that historically served as a critical passage through the region. Water sources, vital for survival in this arid environment, are concentrated at Monument Spring and Monument Springs, feeding the seasonal flow of Monument Cr.

The southwestern portion is dominated by the prominent mass of Elephant Mtn, which rises above the wide floor of Chalk Valley. Drainage patterns here are characterized by ephemeral washes such as Chalk Draw and Maravillas Cr, illustrating the rugged, water-carved geography of the Trans-Pecos. To the north, Black Peak stands near the mouth of Doubtful Canyon, marking the entrance to a network of high-relief ridges and draws.
