Victoria's Hidden Grand Canyon: The Bass Canyon
Hidden beneath the calm surface of Bass Strait lies one of Australia’s most extraordinary geological features: the Bass Canyon, a massive underwater system stretching more than 160 kilometres and plunging over 3000 metres deep just off the Victorian coastline. This blog post uncovers the canyon’s incredible formation story, from cool-water carbonate sediments and ancient mass-wasting events to the powerful Bass Cascade, a cold underwater density current that helped carve this enormous chasm into the continental slope. Explore the science, geology and deep-time history behind Victoria’s hidden Grand Canyon and discover why this submerged giant is one of the country’s most awe-inspiring yet overlooked natural wonders.
