We made our way back to Truro which is a town we passed through yesterday. This area is known for an unusual tidal phenomenon called Tidal Bore, a phenomenon in which the leading edge of the incoming tide forms a wave or waves of water that travel up a river or narrow bay against the direction of the current. The cause is the extremely high tides in this area. The highest tides on planet Earth occur in Nova Scotia's Minas Basin which is where Truro is. The water level at high tide can be as much as 52 feet higher than at low tide! When we passed through here yesterday high tide was just 2 hours away and the bay was nearly dry. Now it is again close to mid-tide. As the water flows out at about mid-tide it equals the combined flow of all the rivers and streams on Earth!
