The glacier-covered Volcán Minchinmávida, located west of Lago Reñihue, has a saddle-shaped summit with an elongated 3-km-wide caldera. The massive edifice is elongated in a NE-SW direction, and a youthful eruptive center is located on the ENE side of the complex. A major explosive eruption at the beginning of the Holocene produced the Amarillo Ignimbrite that may have created the now ice-filled summit caldera, and Holocene tephra deposits from summit and flank vents have been identified. An eruption from Minchinmávida was reported in 1742. Darwin observed the volcano in activity in 1834 on his renowned voyage that took him to the Galápagos Islands. The latest known eruption of basaltic-to-andesitic Minchinmávida, from February to March 1835, produced a lava flow from a flank crater and lahars that reached the coast at Punta Chana.

Glacier-covered Volcán Minchinmávida is elongated along a NE-SW direction. The volcano has a mostly obscured 3-km-wide caldera, and a youthful eruptive center is located on the ENE side of the complex. An eruption from Minchinmávida was reported in 1742. Darwin observed the volcano in activity in 1834 on his renowned voyage that took him to the Galápagos Islands.

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.
