Mount Darwin (Spanish: Monte Darwin) is a peak in Tierra del Fuego forming part of the Cordillera Darwin, the southernmost range of the Andes, just to the north of the Beagle Channel. It is formed of crystalline schists and has massive glaciers down its steep southern slopes. Monte Darwin was for a long time considered as the highest peak in Tierra del Fuego, but that distinction corresponds to a mountain unofficially named Monte Shipton, which is about 2,580 m (8,460 ft) high and is located at (54°39′33″S69°35′54″W). Both peaks are best climbed in late December, January, February and March. Monte Shipton was first climbed in 1962 by Eric Shipton, E. Garcia, F. Vivanco and C.
