A very prominent massif at the head of the Mill Glacier, the highest peak rising to 3200m above sea level. Covereing about 120 square miles in area, this massif is a landmark for aviators flying up the Mill Glacier to the South Pole. The Southern Party of the NZGSAE, 1961-62, which surveyed and named this feature, were landed at plateau level 2 miles to the south east of this massif on 6 November 1961, and climbed the highest peak a few days later, suffering extreme discomfort from altitude sickness. Named for P M Otway of the Southern Party, who had wintered over at Scott Base and had been assistant surveyor with the Northern Party during the summer of 1960-61.
