Michael|last=Hogan|year=2014|url=https://editors.eol.org/eoearth/wiki/Magellanic_subpolar_forests|title=Magellanic subpolar forests|publisher=Encyclopedia of Earth, National Council for Science and the Environment. Washington DC|access-date=2025-01-06}} The Chilean name of Cochrane comes from the nearby town of Cochrane where climbers often approach the mountain. The peak was first climbed in 1943 by Alberto Maria de Agostini.

The mountain is covered by three large glaciers (two in Argentina and one in Chile). The Argentine glaciers show clear evidence of retreat.{{cite web
