The roughly 800-m-wide San Miguel crater is seen here in 2011 with fumaroles in the geothermal area on the far crater wall producing small gas-and-steam plumes. Different colors in the crater walls are from various levels of oxidation and geothermal alteration of the rock. Photo by Lis Gallant, 2011.
