Small cinder cones on the lower SE flank of San Miguel between about 300 and 400 m altitude were constructed along a radial fissure that also was the source of a voluminous basaltic lava flow (foreground) erupted in 1819.  The flow traveled about 5 km and covered a broad area below the base of the volcano. Photo by Paul Kimberly, 1999 (Smithsonian Institution).
