On Aber Mawr Beach , the submerged forest around the Pembrokeshire coast ,
drowned about 6,000 years old , makes an appearance .
And as at Amroth the sand levels need to be low .
The remains are close to the pebble bank.
As the 'Ice Age' came to an end rising sea levels , flooded low coastal areas -
reworking gravels and sands into sandy beaches and shinge ridges
which gradually moved inland covering forests in the process.
A number of other beaches around the coast show this feature - under optimum conditions -
Amroth , Lydstep Haven and at times - Freshwater West , Manorbier , Newport , Newgale , Whitesands , Wiseman's Bridge.
