Fossil - Ice Wedges
At the back of Marros Sands - Carmarthenshire are distinctive vertical streaks of
fine sediments .
The sediment has filled deep cracks formerly occupied by ice.
Ice Wedges are a feature caused when the ground freezes and contracts,
opening up cracks in the permafrost that fill with wedges of ice.
