roche ripple

Its peaks removed by one of the biggest controlled explosions in history and a major feat of engineering on this day in 1958 to mitigate potential navigational hazards and the event covered live in one of the first national, coast-to-coast televised broadcasts, Ripple Rock is a seamount in the Discovery Passage, an inlet between Vancouver Island and the mainland of British Columbia. The geological formation was so named as the summits were only metres below the surface and made a unique standing wave in the fast currents of the strait.
