The Geology Walk starts to the left of the Loch Ard Gorge parking lot. Within about 650 feet you reach a viewing platform called the Tom and Eva Lookout. Its namesakes are Thomas Pearce and Eva Carmichael, the lone survivors of the Loch Ard shipwreck. In front of you was Island Archway. But why are there two pillars of stone here instead of an arch? Because Island Archway collapsed in 2009. Some folks now call them Tom and Eva.
