Isla San Martín, 6 km off the west coast of Baja California, is the westernmost volcano of the San Quintín 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.

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.

The Volcán Sudoeste cinder cone and smaller cones at its base are part of the San Quintín volcanic field in México'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 Quintín volcanic field. It lies on a narrow peninsula between the Falsa bay (left) and the Pacific Ocean (right).

Volcán Sudoeste, one of a group of young pyroclastic cones of the San Quintín volcanic field, is located at the head of a narrow peninsula jutting into the Pacific Ocean. Volcán Sudoeste, seen here from the north, may have initially been an island. The sand bars along the coast, formed by longshore currents, connect Volcán Sudoeste to Monte Mazo, at the southern end of a 10-km-long sand spit.

A vertical aerial photo shows the nested craters of Volcán Riveroll (right-center) and the intersecting craters of Volcán Basu (below and to the left). The Riveroll craters are breached to the NW (upper left). Dark-colored basaltic lava flows extend to the SE from both cinder cone complexes. The flow from Riveroll diverts around the Kenton cinder cone at the lower right. The light-colored areas are windblown sand. The Pacific coast shoreline is at the left, and the body of water at the upper right is part of San Quintín Bay.

Volcán Riveroll, seen here from the NE, is the northernmost of the southern group of cones of the San Quintín volcanic field. A broad crater truncates the summit of the cinder cone and is breached widely to the NW. A smaller nested crater, itself breached to the NW, was constructed within the original crater and is the youngest feature of the volcano.

Volcán Ceniza (left) and Volcán Kenton (right), seen here from near Chapala, are two of a group of young cinder cones in the southern part of the San Quintín volcanic field in northern Baja California. Along with the Riveroll cone to the NW, they are constructed along a NW-SE line, one of several fracture patterns in the San Quintín field. The two cones form a peninsula jutting into Bahia Falsa, part of which is visible at the left.

A vertical aerial photograph shows the small, roughly 1-km-wide Isla San Martín, the westernmost of the small volcanoes of the San Quintín volcanic field. Isla San Martín lies 6 km off the Pacific Ocean coast from the rest of the volcanic field and consists of a small basaltic shield volcano capped by a less than 40-m-high cinder cone. The peninsula at the SE (lower right) side of the island is formed by a lava flow.

The Woodford group (Ieft) and Media Luna (right), seen here from the SSE, comprise the northern group of cones of the San Quintín volcanic field. The Woodford group consists of a closely spaced cluster of breached cinder cones and associated lava flows. The large cone of Media Luna is breached to the east and fed a lava flow in that direction.
