Features

Fluted Peak

. A fluted snow peak rising at the southeast extremity of Roberts Massif. The only snow peak on the massif, it is visible for many miles to the south as a distinctive landmark. Surveyed and named by the Southern Party of the NZGSAE (1961–62) because of its appearance.

Grass Bluff

. A wedge-shaped rock bluff northwest of Fluted Peak, in the southern part of Roberts Massif. Named by the United States

air photos, 1960-65. Named by US-ACAN for Gregory L. Fernette, USARP field assistant in Antarctica during the 1968-69 season.

Munizaga Peak

. An ice-free peak, high, located east-southeast of Misery Peak in the Roberts Massif. Mapped by the USGS from surveys and U.S. Navy air photos, 1960-65. Named by the US-ACAN for Fernando S. Munizaga, Chilean geologist who participated in the USARP Ellsworth Land Survey, 1968-69, and accompanied the Texas Technological College geological party in a survey of Roberts Massif in the same season.

Misery Peak

. A peak, high, at the extreme west side of Roberts Massif, occupied as a survey station. So named by the Southern Party of the NZGSAE (1961-62) to describe the many miserable hours spent here while waiting for clouds to disperse.

Everett Nunatak

. A massive rock nunatak standing just northeast of Roberts Massif, at the southwest side of Zaneveld Glacier. Named by the Texas Tech Shackleton Glacier Expedition (1964-65) for James R. Everett, graduate student at Texas Technological College, a member of the expedition who first explored the feature.

Nearby features

Dismal Buttress

. A mainly ice-free rock bluff, overlooking the west side of the head of Shackleton Glacier about NW of Roberts Massif. So named because of several depressing incidents experienced here by the Southern Party of the NZGSAE (1961-62), including the loss of Dismal, the party's only lead dog, which had to be destroyed.

Half Century Nunatak

. A prominent nunatak, displaying a high east-facing rock escarpment, located north of Dismal Buttress at the west side of upper Shackleton Glacier. Named by the Southern Party of the NZGSAE (1961-62) which, near this nunatak, celebrated the 50th anniversary of Amundsen reaching the South Pole.
