Frontier Mountain
Frontier Mountain () is a large, mainly ice-free mountain, high, situated south-southeast of Roberts Butte of the Outback Nunataks, Victoria Land, and west-northwest of the Sequence Hills, near the edge of the featureless, interior ice plateau of Antarctica. It was named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1962–63, because of its geographical location. This mountain lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
