Aden Crater

Aden Crater is a small shield volcano, part of the Potrillo volcanic field of New Mexico.[3] It is in Doña Ana County between Santa Teresa, New Mexico and Las Cruces, New Mexico. It is in a remote location that can be hiked and explored. The area has deep caverns that can be very dangerous to inexperienced hikers and cavers.[5] A fossilized ground sloth,[6] now at the Peabody Museum, was found in a fumarole roughly 100' deep located on the SE portion of the crater rim. Several ground sloth coprolites were also recovered and were stored in the Geology department at UTEP.
