"A Walk into a Volcano " a Capulin Volcano National Monument Travel Page by niamey00

Capulin is the cone of a volcano that erupted between 56,000 and 62,000 years ago. In the greater volcanic area, called the Raton-Clayton volcanic field, there were three main periods of volcanic activity. Capulin formed during the last of these periods. The cone rises 1300 feet above the surrounding plans to 8182 feet above sea level.
Legend has it that the volcano was named after the Spanish word for chokecherry.
Capulin is extinct. But although it will never erupt again, the formation of a new cinder cone in the Raton-Clayton volcanic field is probable sometime in the future.
