Ripple Rock is an underwater mountain located in the Seymour Narrows of the Discovery Passage in British Columbia, Canada. It had two peaks that produced large, dangerous eddies from the strong tidal currents that flowed around them at low tide. Ships transiting the strait preferred to wait until slack tide in order to safely bypass the rock.
