1993 Map of Riley Canyon

About this map

The Purgatoire River carves a deep, winding path through this rugged corner of Colorado, defining a landscape where ranching history and modern military activity converge. In the early 1990s, much of this terrain was managed as part of the Comanche National Grassland, yet the southern reaches transition into the Fort Carson Military Reservation (Piñon Canyon Maneuver Site). The isolation of this canyon country is evident in the sparse network of dirt routes like Rourke Road and family-named landmarks that point to a lineage of high-plains settlement.
