Reversing Rapids

Right at the doorstep of Saint John, the Bay of Fundy’s monstrous tides bring spectacle to life. Hundreds of millions of years ago, continents collided, forming the gorge through which the St. John river flows. When the world’s highest tides push in, rushing up and over the river, they collide, and the river actually reverses in the face of this unstoppable natural power. Then, as the water begins to drop with low tide, the river empties freely into the Bay, and the full flow of the St. John River thunders through the gorge once more.
