Little is known of this isolated volcano that was seen in eruption by Darwin. Corcovado, probably of late-Pleistocene age, is eroded by glaciers and surrounded by Holocene cinder cones. A series of lakes flank the eastern side of the basaltic to basaltic-andesite volcano. Eruptions in historical time were considered likely from these postglacial volcanoes (Moreno 1985, pers. comm.). Darwin observed activity from the Corcovado area in 1834, and an eruption was reported to have occurred in November 1835.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The dramatic summit spire of Volcán Corcovado is seen here in an aerial view from the south. Two of a string of lakes on its eastern side appear in the background. Corcovado, probably of late-Pleistocene age, is eroded by glaciers and surrounded by Holocene cinder cones. Eruptions were reported in historical time from these flank cones. Darwin observed activity from the Corcovado area in 1834, and an eruption was reported to have occurred in November 1835.

The dramatic summit spire of Corcovado volcano is seen in this telephoto view from the west from the town of Quellon on the island of Chiloe. The volcano rises across the Gulf of Corcovado, which lies beyond the ridge in the middle distance. The main edifice at Corcovado is likely Pleistocene in age, but historical eruptions have been reported, probably from Holocene cinder cones surrounding the volcano.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
