Valles Caldera
NEW MEXICO·NHAP02
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.
