Nature
Capulin Volcano is an extinct cinder cone in northeastern New Mexico and one of the best-preserved features in the Raton-Clayton volcanic field. Formed roughly 54,200 years ago by intermittent Strombolian eruptions, it rose about 500 meters above the surrounding plains, with winds shaping its asymmetrical cone and lava later spreading from a weak point at its base. Its crater, rim, spatter deposits, and pressure ridges remain remarkably intact despite erosion, making it an unusually clear example of cinder-cone structure. Protected federally since 1916, it is valued for both geologic significance and a distinctive high-plains woodland habitat with notable plant and animal species.
