The Glass Mountains dominate the northwestern landscape of this Pecos County region, where the terrain breaks at the significant passage known as Marathon Gap. This high-desert environment is characterized by dramatic elevation shifts and seasonal drainage systems like Sixshooter Draw and Nineteen Draw. Transportation through this isolated territory is anchored by the presence of US Route 385, which follows the natural corridor through the gap, and secondary routes such as Longfellow Rd and the historical Wagon Rd.
