Flooded slate quarry, Swithland Woods, Watercolour/mixed media, 11x14 ins approx, Vivien Blackburn
The pale colours here in the ground are a little bleached out - they should have a pale pink/amber colour.
I've been looking at the old flooded quarry near Swithland woods in watercolour and coloured pencil.
The slate that was quarried there is very ancient pre-Cambrian rock - the oldest rocks in Britain. Until recently it was thought that no fossils were preserved in this ancient rock - but recently fossils of ferns have been found (details of this and the geology and history of the area are in the links below).
It's thought that the woods are the remains of primeval forest, having been there from at least 5,000BC.
