I’m standing 918 feet above ground level, with nothing but three layers of inch-thick glass between me and the snow-covered valley floor below. I spot a goat doing what goats do, clinging to a near-vertical cliff face. All I can think about is how they look considerably more confident than me. This is Jasper National Park’s newly-opened Glacier Skywalk, a platform of curved glass which is secured to the rock face by steel rods which penetrate 52 feet into the mountainside. It is suspended over the Sunwapta Valley in the heart of the breathtaking Canadian Rockies and between the ski towns of Banff and Jasper.
