Comment:
Taken on 3 January 2014, this photograph is looking approximately
northeast towards Wadhead Scar at Bardsea on the western shore of
Morecambe Bay. Wadhead Scar is the apparent cliff of earth
seen on
the right of the photograph. The erroded mound is, in fact, a
kame, which is a sub-glacial bedded deposit of various grades of 'sands'
and gravels left by the last ice age. Over the many thousands
of years since the ice melted the large deposit has
been erroded away by numerous but infrequent occasions when it was
pounded by sea conditions such as seen here, which require the
combination of a high tide, a nearby area of deep low atmospheric
pressure, and accompanying strong winds. The outcome of the destructive high
force of waves breaking onto the shore as seen in this photograph is illustrated in later
photos in this series.
