Valles Caldera

NEW MEXICONHAP02

A collapsed volcano in the Jemez Mountains of northern New Mexico. Valles Caldera is a bowl roughly fourteen miles across, formed in an eruption over a million years ago, with forested lava domes rising from open grass valleys. On infrared film the structure declares itself: conifer forest in deep reds and maroons, with flat meadow floors read pale, and outlines from the caldera rim and roads.
