Abstract

Frozen ground phenomena in the Northern Foothills, Northern Victoria Land, include large-scale polygons, 15-20 m in diameter, and small frost mounds, 1-5 m high. The polygons are most widespread on terrain formed upon Younger Drift and are usually surrounded by interpolygon furrows or troughs, 10-30 cm deep and 10-100 cm wide. Field and anecdotal evidence suggest that thermal contraction cracking is active under today's climate. Frost mounds occur in association with a number of perennially frozen lakes in the region. In most cases they appear related related to frost and icing blister activity caused by the episodic injection of free water from below
