Welcome to Commonwealth Bay & Cape Denison


The same furious katabatics that caused Mawson to call this the ‘Home of the Blizzard’ often make landing here impossible. They also make conservation of Mawson’s huts (www.mawsons-huts.org.au) much more difficult than that of the historic buildings on Ross Island. In 2007 a small laboratory was built to help conserve the site’s artifacts. Areas between the Main Hut and Boat Harbor where artifacts (building materials, domestic and scientific equipment, food, packaging, clothing and other historic detritus) are scattered on the ground are off-limits to tourists. No more than 20 people at once may come ashore here.
