The Cinder Cone Wilderness is part of the Greater Potrillo Mountains Complex, located approximately 30 miles southwest of Las Cruces adjacent to the border with Mexico. This wilderness features an extremely high concentration of cinder cones giving evidence of its past volcanic history.
Chihuahuan Desert grassland and yucca, in association with a mosaic of other desert shrubs such as creosote, acacia, and mesquite, make up the majority of the plant cover in the area. Isolated clumps of netleaf hackberry and other desert trees are found in the lava flow where depressions or deeper pockets of soil hold extra water after rainfall. Occasional juniper trees are also found on mountain slopes and in larger drainages. Summer monsoon rains bring extensive stands of wildflowers in this area including white and yellow desert zinnias, desert marigolds, blackfoot daisies, globe mallow, pepperweed, desert sunflowers, Chihuahuan flax, and summer poppy. Unusually large specimens of barrel cactus also live in this area.
Raptors are common, especially during the winter. Golden eagles, great-horned owls, and Swainson’s hawks nest here, and peregrine falcons have also been reported. Other species that forage and live in the area include pronghorn, mule deer, quail, jackrabbits, and occasional migrating ducks on ephemeral ponds.
The south and western part of the Greater Potrillo Mountains complex is easily reached by Highway 9 that goes from Santa Teresa to Columbus along the border with Mexico. From I-10 exit #8 in Texas, head west toward the border crossing on Highway 136. Just north of the border, about 9½ miles southwest of the interstate exit, turn west on Highway 9. In 16½ miles, CR A008 comes in on the north. This road forms the eastern boundary of the East Potrillo Mountains unit.
