In an instant, 28 homes were crushed on Sept. 19, 1889, when a huge piece of rock broke off Cap Diamant in Quebec City and slammed down, burying about 100 people. The rockslide killed 48, but could have been much worse — many who lived on the street were away. The worst rockslide in Canadian history occurred in Frank, Alta., on Apr. 29, 1903. In just two minutes, millions of tonnes of rock rumbled down Turtle Mountain, covering nearly two square kilometres including the entrance to a nearby mine and most of the town. About 70 of the town’s 600 or or so people died; because rescuers couldn’t find everyone, we’ll never know for sure. The Jane Slide happened in the village of Britannia near Squamish, B.C. on Mar. 22, 1915. Mud, rock and snow 15 metres deep in places crashed down the nearby mountain, destroying cabins where miners and their families were sleeping. Rescuers dug hard and long, but at least 50 people died.
