Mount Ollivier [SEP] Introduction
Mount Ollivier is a mountain in the Canterbury region of New Zealand. It is a peak in the Sealy Range, about west of Mount Cook Village. The peak is named after mountaineer Arthur Ollivier, who died in 1897. Mount Ollivier was Sir Edmund Hillary's first major climb, in 1939. After his death in 2008, there was a proposal to rename the peak Mount Hillary as a memorial, a suggestion opposed by Arthur Ollivier's family. Since the establishment of a tramping track to Mueller Hut, not far below the summit, the peak is now one of the easiest accessible mountains in the park.
