These pictures are taken about 5 minutes from where I live. This is a tidal river that connects to the Bay of Fundy. These tides happen twice a day, so you have a low tide and a high tide every 6 hours. Amazing to see the difference. You can actually watch the tide come in and out. In some areas up here they have "tidal bore rafting", where they take you out in a rubber boat and you can ride the biggest wave of the tide, "the bore", in. There was a guy there today fishing for striped bass and eel.
