The Valle de Santiago in the NE part of the Michoacán-Guanajuato volcanic field NW of Lake Yuriria contains a group of youthful maars formed by phreatomagmatic eruptions.  The maars, four of which are lake-filled, range from 0.8 to 1.8 km in diameter and are 80 to 180 m deep.  They were formed very recently and are of probable Holocene age.  This photo shows the Hoya Rincón de Parangueo maar at the northern end of the maar field. Photo by Jim Luhr, 1982 (Smithsonian Institution).
