Sand dunes at Tetney Marshes nature reserve, looking out towards the Humber estuary. In the distance can be seen the two sand forts, the nearer one Haile, close to the centre of the picture, with the more distant Bull to its left. Also on the horizon are various ships at anchor, waiting for the tide before proceeding up the Humber to Grimsby, Immingham and Hull. For more information about the nature reserve, with its varied habitats, see TA3304 : RSPB Tetney Marshes.
