This photograph is taken from the sands of Morecambe Bay looking west to the Furness peninsula at Aldingham.  The sands of Morecambe Bay extend to around 310 km² and along this western coast are occasionally punctuated by stoney scars, one of which is seen in this photograph.  These are remnants of debris dumped by the last glacier to pass over the bay and the local peninsulas around 14000 years ago.  The earth bank on the distant shoreline is an eroding mound of glacial debris which continues to slowly deposit its rocky content onto the beach where the tidal waters wash away the glacial till which shared places with those rocks within the parent drumlin.  Under the influence of tidal currents the sands of the bay are constantly shifting and at any point varying in depth over time, so over the long term the stoney scars vary in their prominence.  Around the bay there will undoubtedly be many such rocky deposits which are permanently buried beneath the sand.
