2016 Map of Bone Spring

About this map

Rosillos Mountains dominate the southwestern quadrant of this Brewster County landscape, rising sharply to the summit of Rosillo Peak. This high ground transitions into a sprawling basin defined by complex drainage networks, where Santiago Draw and Nine Point Draw move seasonal runoff through the arid terrain. Much of this area is protected within the northern reaches of Big Bend National Park, a region where the geography is shaped more by water sources and elevation than by settlement. Vital water points such as Bone Spring and San Juan Spring are noted alongside the intermittent courses of Chalk Draw and Bone Spring Draw. Transportation across this remote desert environment is limited to significant corridors like Marathon Rd and Main Park Rd, which provide access to the interior of the park and the surrounding Trans-Pecos wilderness.
