Location
The Helliwell Hills are part of the Usarp Mountains of North Victoria Land, Antarctica. They are south of Gressitt Glacier and midway between Emlen Peaks to the west and the Morozumi Range to the east. They are south of the Daniels Range, on the other side of Gressitt Glacier, and north of the Outback Nunataks.
Early exploration and name
The Helliwell Hills were mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos in 1960-63. They were named by the Advisory Committee on Antarctic Names (US-ACAN) for Robert A. Helliwell of Stanford University, Program Director for the USARP study of very low frequency (VLF) radio noise phenomena.
Geology
The cover rocks in the Helliwell Hills are Permian Beacon sediments and Jurassic Ferrar sills. The basement has low- to high-grade metamorphic rocks as well as pegmatite and granites. There is a fairly continuous transition from low to high grades in the metarnorphic rocks. This is evidence for intense local heat during metamorphism. The degree of metamorphism, deformation and pegmatite formation increases greatly from east to west in the hills. The phyllites at the lowest level in the east of Boggs Valley are similar to the rocks of the Morozumi Range, with simple deformation. Further west the deformation is more polyphase, and at least three phases of folding can be recognized in the west.

Named features from north to south:
Dziura Nunatak
Mount Remington
Mount Bresnahan
A flat-topped, mainly ice-free mountain, 1,630 m high, situated along the east side of the Helliwell Hills, 6 mi north-north-east of Mount Van der Hoeven. Mapped by USGS from surveys and U.S. Navy air photos, 1960–63. Named by US-ACAN after David M. Bresnahan, USARP biologist at McMurdo Station, 1967–68 and 1968–69; on staff of Office of Polar Programs, National Science Foundation, from 1970.

Mount Alford
A flat-topped, ice-free mountain, 1,480 m, at the south side of Boggs Valley in the Helliwell Hills. Mapped by USGS from surveys and U.S. Navy air photos, 1960–63. Named by US-ACAN for Montague Alford, USARP geologist at McMurdo Station, 1967-68.
