Islote Negro

Small camp on the southern end of the island.

1.1-ha (2.7-acre) islet about a mile south of a major landslide and a couple miles south of Campo Oeste.

Another barren islet, located near Roca del Skip and Church Rock.

The most distant island, steep with almost vertical walls above and below water

The main settlement with about 200 people, Oeste is a small community of abalone and lobster fishermen, on the western coast. It is on the north side of West Anchorage, a bay that provides protection from the strong winds and swells that whip the islands during winter. Generators provide electricity, and a desalination plant provides fresh water. The 30 families of a fishing cooperative live here ten months of the year .

At an elevation of 975 meters (3,199 ft), El Picacho is the highest point on the southern side of the island. It is on a desert ridge which sits above Campo Oeste.
