The Aden Lava Flow WSA is located 20 miles southwest of Las Cruces in the Chihuahuan Desert. The area is characterized by basalt flows, volcanic craters, and coppice sand dunes. The lava flow includes pressure ridges, lava tubes, and steep-walled depressions of up to 100 feet wide. Grass and shrubs grow on the flow with many cacti and yucca. Vegetation consists of grasslands and desert shrubs such as mesquite and creosote. Vent tubes, and the many crevices found in the lava, provide cover and den sites for wildlife. Bats are numerous and the rock pocket mouse and black-tailed rattlesnake are found on the black lava flows.
