The Abbot Pass hut stood for decades in a rugged saddle between two iconic peaks, overlooking the limpid turquoise of Banff National Park’s Lake Louise – a destination for alpinists from around the world until the ground melted beneath it and forced its closure.University of Calgary researchers have now used a century’s worth of entries from the hut’s log to illuminate how climate change is erasing historic climbs, making others more dangerous and altering the face of Canadian mountaineering.
