as you remember from our last post, we are on our way to Massachusetts to see friends before heading back to Ontario. Along the way we came through Truro, Nova Scotia and New Brunswick and we couldn't resist to go see two really interesting sights with regards to tides: the tidal bore in Truro and the world's highest tides here in Hopewell Cape.
A tidal bore is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay against the direction of the river or bay's current. It can be just a very small wave, no more than a few inches or a bigger one. The one in Truro is not huge but big enough to clearly see it coming and what's impressive, is the speed with which it moves and fills the riverbed. In order to give you an impression of what we've seen we have included two pictures which were taken only about 20 Minutes apart. In the second picture the water is actually a few feet deep.
Our next stop was in Hopewell Cape in New Brunswick where one can witness the world's highest tides. The difference between low and high can be as much as 14 meters (46b feet). On the evening of August 31 we were down there walking on the ocean floor and the next day around noon we returned to see the same rock formations at high tide. It wasn't the highest possible that day. According to a park ranger it reached "only" 13 meters (43 feet) and left a small gap in the arch between two rocks. This can hardly be seen on our pictures but nevertheless they give an idea of the change. We were awed by this display of nature and will not forget looking down to where the night before we were walking and now there was several meters of water.
