The tourist literature talks up the twice-daily return of the waters of the tidal Petitcodiac River. In theory, the tide comes in as one solid wave, unfurled like a carpet across the muddy riverbed in one dramatic gesture. As the tide advances up the narrowing bay it starts to build up on itself, pushed from behind by the powerful tides in the Bay of Fundy, the world's highest. The height of this oncoming rush can allegedly vary from just a few centimeters to about 1m. In reality, it usually just looks like a big mud seep, and is, well…boring.
