Aden Crater en
Aden Crater is a volcanic crater, part of the Potrillo volcanic field of New Mexico. It is in Doña Ana County between Santa Teresa, New Mexico and Las Cruces, New Mexico. The crater 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 spelunkers. A fossilized ground sloth, now at the Peabody Museum, was found in a lava tube here. No volcanic activity at Aden Crater is known from historic times. The most recent known activity has been dated to roughly 16 kya. Wikipedia [ - ]
