The Helliwell Hills are a group of rocky hills and low mountains that extend over a length of approximately 29 km and a width of 14 km in the Usarp Mountains in northern Victoria Land. They are located south of the Gressitt Glacier and halfway between the Emlen Peaks and the Morozumi Range .

The geodetic survey was carried out by the United States Geological Survey and using aerial photographs of the United States Navy from 1960 to 1963. The Advisory Committee on Antarctic Names named it in 1964 after Robert A. Helliwell (1920-2011) of Stanford University , who in the frame of the United States Antarctic Program conducted studies on low-frequency ionospheric signals .

Fossils

During the GANOVEX XI expedition in the Antarctic summer of 2015/16, scientists found an Ichnofossil in the Helliwell Hills, which are assigned to the Beacon Supergroup , which is assigned to the Ichnogenus Procolophonichnium (group of the Procolophonoidea ). It comes from the early Permian or the early Triassic and is the largest known Ichnofossil of this Ichnogenus.
