Mt. Capulin National Monument, New Mexico
The park headquarters and visitors center are visible in the left foreground, and Mt.
Capulin appears on the horizon to right. Mt. Capulin in a "scoria cone" type of volcano
built of tephra (volcanic ash and bombs) erupted from a central vent. This was the
youngest eruption in the Raton volcanic field of northeastern New Mexico. Most recent
dating, based on argon-argon and cosmogenic isotopes, indicates that Mt. Capulin was
formed about 60,000 years ago. Photo date 3/98; © J.S. Aber.
