Small sand-dune accumulating in the lee of sea shell oject lying on the inter-tidal beach at St Annes, Fylde Coast, UK

---

Sand dunes develop where wind blown sand accumulates in the lee of an object, where the wind speed is slowed, causing sand deposition. For a large dune system to develop specialised dune-building grasses, such as marram grass, are needed. This small, temporary dune, has built up at an obstruction (Razor clam shells), slowing the wind, in the inter-tidal zone. The size of this dune is limited by the height of the object.
