Tidal Bore
The channels are constantly changing and consequently not shown on the OS map. Here the tidal bore is coming up a channel, one of several such channels in the estuary, on its way to Arnside some 8km away as the tide flows. It took 2 hours and 5 minutes to reach the viaduct at Arnside (shown in SD4579 : Arnside Viaduct) from this point.
