San Quintin Volc Field

San Quintin Volc Field

Isla San Martin, 6 km off the west coast of Baja California, is the westernmost volcano of the San Quintin volcanic field and the only one that is located offshore. The 2-km-wide island is a small basaltic shield volcano that is capped by scoria cones that rise to 230 m above sea level. Wave erosion has truncated part of the shield volcano, forming the sea cliffs seen at the left on the south side of the island.

The Volcan Sudoeste cinder cone and smaller cones at its base are part of the San Quintin volcanic field in Mexico's Baja Peninsula. They are seen here from the north on the slopes of Picacho Vizcaino. Volcán Sudoeste is one of the youngest scoria cones of the San Quintin volcanic field. It lies on a narrow peninsula between the Falsa bay (left) and the Pacific Ocean (right).
