Coverack Cove
A view to the North East and Lowland Point from the road to Coverack Harbour / Lifeboat station .
A small sand and pebble beach is sandwiched between extensive rocky areas .
The rocks to the south and near the Harbour are of Serpentinised Peridotites from the Earths Mantle -
lifted tens of kilometres by colliding continents 380 million years ago.
Halfway across the beach the rocks change to a mixture of Serpentine ,Troctolite and Gabbro -
a transition zone - 'Moho.'
