This is the view southwest across Laguna del Maule, Chile, from near the summit of the vent for the Holocene rhyolite flows of Cari Launa at 3030 meters above sea level. The 1.2 cubic kilometers of brown glassy lava comprising the central lakeshore in the middle of the photo is the late Holocene rhyolite coulée of Las Nieblas, whose vent is 12.7 kilometers away. The center of maximum uplift measured using InSAR geodesy is in the bay just to the right (north) of the Nieblas rhyolite.
