The South Riding RV Travels

06th August 2007 - Truro NS to Lunenburg NS - Tides

The Bay of Fundy is famous for having the highest tides in the world. Part of the reason is the shape of the bay. Truro is almost at the head of the bay and is famous for its 'bore'. As with the Severn bore in England, the water comes up the river completely reversing the flow approximately one hour before high tide.
The bore can range from a few inches to over a foot depending on the weather and the phase of the moon. The river is quite shallow here and as the water comes round the curve it floods the mud flats where the seabirds have been only moments before. This reduces the height of the wave as it spreads over the width of the river flooding the shallower sides.
The water behind the wave can be quite turbulent as the water bounces off the banks. Further downstream you can take a tour out in an inflatable and 'surf' the wave.
As the river narrows where there used to be a bridge the surge height increases and the following turbulence is more intense. The whole event is over in a couple of minutes but dozens of tourists and locals were there to watch.
The following day we moved on and the river was at low tide, wide and mainly mud flats.
We went up to Burncoat Head on the Bay of Fundy itself. At this point, the highest tide ever recorded was 54 FEET.
It seems a little hard to believe at the head of a bay which should have been quite sheltered. However you can see where the waves had eroded the sandstone cliffs. The bay is 250 miles long and up to 75 feet deep. The water rises over an inch a minute when the tide is coming in. During each tide 100-150 cubic KILOMETRES of water enter the bay from the ocean.
We wandered around the rock pools and watched a bald eagle but somehow never got close enough to get a useable photo. Perhaps that is how it should be.
He is out there at the water's edge, visible by binoculars but now only a pixel high. This will all be covered at high tide.
Back through the woods we spotted this gall on a tree. They are not uncommon but I don't know what causes them.
A last view over the bay with New Brunswick in the distance. We headed east for the other coast of Nova Scotia and the sailing centre of Lunenburg.
