A bushwalker admires Cradle Mountain reflecting in Dove Lake, in Cradle Mountain - Lake Saint Clair National Park, Tasmania, Australia. The Tasmanian Wilderness was honored as a UNESCO World Heritage Site in 1982, expanded in 1989. The most extensive dolerite formations in the world dominate the landscape of Tasmania, where magma intruded into a thin veneer of Permian and Triassic rocks over perhaps a million years during the Jurassic breakup of supercontinent Gondwana in the Southern Hemisphere, forming vast dolerite/diabase sills and dike swarms. (North American geologists use the term diabase instead of dolerite to refer to the fresh, unaltered rock.) Published in Wilderness Travel 2008 Catalog of Adventures.
