In roughly 100 seconds, 110 million tons of limestone broke from the peak and roared down onto the sleeping town of Frank, Alberta. The slide buried the southern end of town, part of the coal mine, a railway, and everyone caught in its path. At least 70 people died - the exact number was never determined because some bodies were never found. The debris field spread nearly three kilometers across the Crowsnest Valley floor, burying the landscape under 30 meters of shattered rock. Today the Frank Slide looks exactly as it did 120 years ago: a chaos of gray boulders covering the valley floor, the scar on Turtle Mountain still raw, a memorial to the 100 seconds when gravity did what gravity eventually does.

Witnesses described a roar like thunder, a blast of wind that knocked buildings flat, then silence as the dust settled on a transformed landscape. The rock traveled at 100 kilometers per hour, crossing nearly three kil...

The coal mine reopened within weeks; Frank was rebuilt, though never recovering its former size. The railway was rerouted over...
