Photo by Jim Luhr, 1990 (Smithsonian Institution). San Quintín volcanic field on the NW coast of Baja California contains lava shields capped by youthful scoria cones. This view looks south from Volcán Basu to Picacho Vizcaino (surrounded by young lava flows), and Volcán Sudoeste (upper left). These are among the youngest features of the San Quintín field. Along with Monte Mazo to the SSE, they are constructed along a N-S line.
