Background

San Félix Island, 800 km W of the Chilean coast, consists largely of a low, cliff-bounded lava platform separating two tuff cones. The Islota Gonzáles cone to the SW is separated from the main island by a shallow submerged platform. Cerro Amarillo at the western end forms the high point of the island and is the source of fresh-looking hawaiite lava flows that reached the sea and formed the low lava platform at the SW tip of the island. A ship captain reported a dull red glow at the summit in 1923. Willis and Washington (1924) considered the youthful lava flows to predate discovery of the island in the 16th century, but not be more than a few centuries old. However, Ar-Ar dating by Haase et al. (2000) determined that the adjacent plateau age was 421 +/- 18 ka, and considered the advanced erosion of the island as indicative of several hundred thousands of years of inactivity.
