Hatteras Group: Traverses in both directions between Mount Hatteras and the small peak ("Squab") (first ascent), which biseas the Hatteras-Sugarplum ridge; two ascents of Sugarplum Spire, one via the grotesquely pinnacled southeast ridge (descent by the northeast buttress) and the other via the lower section of the northeast buttress and higher on ledges on the face towards the west.
