1964: primera ascensión al Shishapangma, la decimocuarta montaña más alta del mundo y la más baja de los ochomiles

First ascent of Shishapangma, the fourteenth highest mountain in the world and the lowest of the Eight-thousanders.

In mountaineering and climbing, a first ascent, is the first successful documented climb to the top of a mountain peak or the top of a particular climbing route. Early 20th-century mountaineers and climbers were mainly focused on reaching the tops of notable mountain peaks and the tops of iconic climbing routes by whatever means possible, and often using considerable amounts of aid climbing and/or with large expedition style support teams allowing them to "lay siege" to the climb.
