In honor of Canada"s National Acadian Day, we"re on the shores of New Brunswick as the ocean recedes to reveal the Bay of Fundy"s massive intertidal zone. The tide is a big deal at the bay—more than five times bigger than in most places. Typical tides around the world have a range of 3 to 6 feet, but these waters drop as far as 50 feet from high to low tide.
