English: Derelict boat in the Severn muds at Garden Cliff This is on the north shore of the Severn, in Westbury on Severn parish. Twice daily the tide, the Severn bore, reverses the flow of the river, so the beach under Garden Cliff (to the right of the picture) is not a particularly safe place to walk - one minute dryish land, then comes a rushing noise, and suddenly the river bed is full of muddy water and debris powering upstream. In the background are the hills and woodland of the Forest of Dean around Flaxley.
