2019 Map of Riley Canyon

About this map

The Purgatoire River carves a winding path through this corner of the Comanche National Grassland, where deep canyons and high plateaus define the border between Otero and Las Animas counties. Historic transportation routes like the Barlow-Sanderson Wagon Road suggest the era of western expansion, crossing a landscape dotted with critical water sources such as Antone Spring, Good Pasture Spring, and the Rock Waterhole. In the eastern section, the Ninemile Valley and the Ninemile Canal reflect early agricultural efforts in this arid environment.
