Ripple Rock Explosion

On the morning of 5 April 1958, Canadians gathered around radios and televisions to witness a moment unlike anything they had seen before: the detonation of Ripple Rock in Seymour Narrows, BC. It was, at the time, the largest planned non-nuclear explosion in history. At the centre of this achievement stood Lieutenant Colonel Cyril Burton North (Ret’d), one of the most accomplished and decorated tunnellers the Canadian Engineers ever produced.
