SITE DESCRIPTION:
This site is a disused quarry and a wind eroded crag on Bingley Moor.
There are massive
beds of the Upper Carboniferous Namurian Rough Rock sandstones in the
quarry, which
show large scale cross bedding. The rock stack shows cross bedding which
has been
etched out by wind erosion.
HISTORICAL ASSOCIATIONS:
 EDUCATIONAL
VALUE:
This is a good site for demonstrating styles of cross bedding, measuring
current directions
and for interpreting a depositional environment.
AESTHETIC CHARACTERISTICS:
Excellent views are obtained from the Crag across the middle Aire
Valley which can be
linked to the underlying geology and geomorphological processes.
ACCESS AND SAFETY:
The site is perfectly safe given normal precautions that should
be taken when in the
vicinity of vertical faces. There does not appear to be any
loose rock on the faces but
there is plenty of spoil to examine at the entrance to the
quarry. Limited parking is
possible on the roadside but would be better in the adjacent
public house (Dick Hudson's
- the Fleece) car park. Access to the site from the road is
by public footpath.
