Loch Ard Gorge, Victoria
I'm partway down into the gorge itself in this shot. Loch Ard Gorge was named after the 79.9m (262' 7") three masted square-rigged clipper Loch Ard, which crashed and sunk near here just after 4:00 a.m. on 1st June 1878, on its way from London to Melbourne. 52 people died, but two eighteen year olds—Eva Carmichael and Tom Pearce—were washed into this gorge and survived. As violent as the gorge was this day, a day when the seas weren't rough, it's hard to imagine anyone surviving. Maybe at low tide.
