History of Ripple Rock

Hidden just beneath the surface of Seymour Narrows, Ripple Rock was one of the most dangerous marine hazards on the British Columbia coast, tearing apart ships navigating the Inside Passage for generations. By the 1950s, engineers launched one of the most ambitious engineering projects in Canadian history, tunnelling beneath the mountain and packing it with 1,270 tonnes of explosives. The blast on April 5, 1958 became the largest planned non-nuclear explosion in the world at the time, permanently reshaping Seymour Narrows and making the passage much safer for ships.
