Redondo Peak in the center and Redondito peak on the right are the eastern half of a resurgent dome in the center of the Valles caldera, seen from the SE across the caldera moat, Valle Grande.  The uplifted resurgent dome is formed primarily of densely welded Bandelier Tuff that was uplifted about 50-100,000 years after formation of the caldera.  Cerro La Jara, the small hill on the caldera floor at the middle left, is a small rhyolitic lava dome erupted along ring-fractures.  Photo by Lee Siebert, 1989 (Smithsonian Institution).
