The peak was first climbed by Erhard Loretan, solo over the 2,100-metre-high (6,900 ft) south face, on December 1, 1994.

In 1999, the American climbers Conrad Anker and Jim Donini failed in their attempt over the west ridge.

[3] The third successful ascent was by the Chilean Camilo Rada and Australian Damien Gildea via a new route over the south face in December 2007.

Their GPS measurements on top suggested a height 153 m above the official one.

[2] This mountain is named after Robert Epperly (born 1926) who spent time during the International Geophysical Year of 1957–1958 in Antarctica.
