The now-highest Carstensz Pyramid summit was not climbed until 1962, by an expedition led by the Austrian mountaineer Heinrich Harrer (of Seven Years in Tibet fame, and climber of the Eiger North Face) with three other expedition members - the New Zealand mountaineer Philip Temple, the Australian rock climber Russell Kippax, and the Dutch patrol officer Albertus (Bert) Huizenga. Temple had previously led an expedition into the area and pioneered the access route to the mountains.
