An evening walk with Stosh to check out the mud-flats left at low tide. "On a flood tide, 160 billion tonnes of seawater flows into the Bay of Fundy — more than four times the estimated combined flow of all the world's freshwater rivers during the same 6-hour interval. The vertical tidal range can be over 16 metres — giving the Bay of Fundy the highest tides in the world." A routine that does repeat itself 'like clockwork."
