Ripple Rock
From Wikipedia, the free encyclopedia
Ripple Rock was a submerged twin-peak mountain that lay just nine feet beneath the surface of the Seymour Narrows in Canada. It was a serious hazard to shipping, sinking 119 vessels and taking 114 lives. On April 5, 1958, after twenty-seven months of tunnelling and engineering work, Ripple Rock was blown up with 1,375 tons of Nitramex 2H explosive making it the largest commercial, non-nuclear blast in North America.
The event was broadcast live on Canadian Television. The footage is also regularly screened at the Campbell River Museum.
The gunboat USS Saranac was one of the rock's first recorded victims.
Vancouver band The Evaporators wrote a song about the event and released it on their 2004 album Ripple Rock.
