Following its 7 km flow from Urswick
Tarn, Gleaston Beck is seen entering Morecambe Bay at Leonard Point on the
east side of the Furness peninsula. On its journey the flow
has been added to by surface water land drainage together with a
significant flow from within the very large drumlin called Beacon
Hill which emerges in the vicinity of Gleaston Castle and which has
been referred to in earlier Pictures of the Month. The curvateous skyline
hills to the left of the photograph are part of the extensive
drumlin field, full of till and stone, brought by a succession of ice
age glaciers from the carved out valleys around Coniston in the
southern Lake District. Right of centre is a closer drumlin
which has been severely eroded by the sea and weather revealing its
content of predominantly volcanic rocks rounded during their passage
within and beneath the ice. The similar erosion of other
drumlins in the period since the end of the last ice age, around
11700 years ago, has left the stone now covering the shoreline and
the occasional rock
covered scars along the coast of the bay. The more distant
hills forming the skyline on the right of the photopgraph are on the
neighbouring Cartmel peninsular. Also seen in the picture is a
small part of the very extensive inter-tidal exposure of sand for
which Morecambe Bay is renowned, along with its treacherous tidal
flows that have claimed the lives of many.
