SITE DESCRIPTION
The
site contains exposures of the Doubler Stones Sandstone of Upper Carboniferous
Namurian age which displays a range of structural and weathering features.
The two rock stacks contain well preserved cross bedded structures
and areas of
honeycomb weathering. The rock is a coarse, pebbly gritstone which
forms the capstones
of the stacks with underlying beds of friable material displaying extensive
weathering,
probably by sand-laden wind abrasion in a periglacial environment towards
the end of the
last (Devensian) glaciation.
HISTORICAL ASSOCIATIONS:
EDUCATIONAL VALUE:
The quarry has interesting geological features, while the Doubler Stones
allow discussion
of periglacial weathering processes.
AESTHETIC CHARACTERISTICS:
This is a spectacular site, with views to the south and west. The
second rock stack is not
seen from the track and only becomes apparent once the observer
is at the same level as
the top of the quarry.
ACCESS AND SAFETY:
It is possible to park on Lightbank Lane (SE 062 470). Walk south
west along Lightbank
Lane to SE 066 463; turn east following the farm access road
to Doubler Stones. There is
no access to the site by wheelchair.
