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. Aerial photo by Comisión de Estudios del Territorio Nacional (CETENAL), 1:25,000, 1999.
