Santa Ana's active crater, partially filled by an acidic crater lake, lies at the SE end of a series of four nested craters.  This photo is taken from the northern rim of the next-to-youngest crater and shows a broad bench whose surface is dotted by several small phreatomagmatic vents formed during historical eruptions.
