 The North Somerset Levels are to the east of Weston-super-Mare, while the Axe valley is separated by the Isle of Wedmore from the Brue valley. The latter is separated by the Polden Hills from the main wetland of the Parrett / Tone / Cary valleys. The Poldens are a low narrow ridge of Blue Lias with alternating bands of limestone and clay. Because of the nature of the Levels and Moors, the Poldens have a significant visual impact.
