Volcanoes of the San Francisco volcanic field

This aerial shot by Ted Grussing shows several of the prominent vents from the central-eastern San Francisco volcanic field. The San Francisco Peaks is a long lived composite volcano, Mt Elden is a exogenous, dacite dome. The majority of vents in the field are monogenetic, short-lived cinder cones, such as Sunset Crater. The eastern part of the field formed during the Pleistocene and Holocene.
