Photo Gallery

Isla Isabel, a complex of cones and associated lava flows, forms a small 1.5-km-long island located in the Pacific Ocean 30 km off the coast of Nayarit state, Mexico. The island is seen here from the SE with Cerro el Faro cone to the left and the spires of the Islotes Las Monas to the right. Isla Isabel is a wildlife sanctuary whose rocks and vegetation are mantled with white guano. Exposures of the interior of the cones forming the island can be seen in the main island sea cliffs and offshore islets.

Wave erosion of a tuff cone off the western coast of Isla Isabel has produced the jagged profile of the 100-m-wide southernmost sea stack in the Islotes Las Monas. The three guano-covered cone remnants forming the Islotes Las Monas lie within about 200 m of the eastern coast of Isla Isabel, which can be seen to the right.

A sea-cliff exposure at the southern end of Islota Pelón, located off the NW coast of Isla Isabel, shows a dramatic angular uncomformity between two generations of dipping tuff beds. The large volcanic bomb perched on the rim at the top lies on dipping layers in the interior of the tuff cone. Wave erosion has left only the arcuate western rim of Islota Pelón, whose vent lies out of view to the right.

Islota Pelón (upper left), just off the NW coast of Isla Isabel, is the outer rim of a mostly submerged cone whose SE rim (center) is located on the tip of the main island. A narrow lava flow seen diagonally from the lower right to the bay is part of the Planicie lava flow and is the product of the youngest eruption on Isla Isabel.

The flat-topped Cerro El Faro cone (upper right) lies across a low isthmus at the southernmost tip of Isla Isabel. It is seen here across the Acantilado Mayor Bay from Cerro del Mirador, the high point of the small 1.5-km-long island. Wave erosion has eroded the flank of Monte Transverso to the left. The two cones are connected by a lava flow.

A biological research station and fishermen's shacks line the shores of Playa Chica on the SE side of Isla Isabel in this 1999 photo. The two spires to the upper left are the Islotes Las Monas, eroded remnants of an offshore cone. The lake-filled Laguna Fragatas maar can be seen at the left in front of the spires of the Islotes Las Monas. The small 1.5-km-wide uninhabited Isla Isabel is a wildlife sanctuary.
