Colachi (left) is an andesitic-dacitic stratovolcano whose most recent activity produced pristine silicic lava flows of probable Holocene age.  The largest of these covers a 7 sq km area on the saddle between Colachi and the neighboring volcano of Acamarachi (center horizon).  This aerial view from the west also shows the conical peak of Aguas Calientes (far right), a twin volcano of Lascar volcano, whose slopes appear at the lower right.  The Talabre valley in the center foreground is partially filled by an andesitic lava flow from Lascar.
