MOST RECENT SURVEY
SITE DESCRIPTION:
Exposures of Upper Carboniferous East Carlton Grit (Scotland Flags) are
revealed in abandoned delph holes located on moorland overlooking the
Calder Valley. The rock varies from well bedded sandstone to fissile
siltstone. Only a few horizons display flaggy bedding with micaceous
partings. The site contains much discarded material where ripple marks,
trace fossils and examples of Lepidodendron bark can be seen.
HISTORICAL ASSOCIATIONS:
Of further interest is a prehistoric earth circle located adjacent to
the site.
EDUCATIONAL VALUE:
Not suitable for large parties because of rough terrain and disturbance
to wildlife habitat.
AESTHETIC CHARACTERISTICS:
Excellent views across the Calder Valley toward Cragg Vale and Stoodley
Pike.
In common with other moorland sites above the Calder valley, Foster Clough
Delves is favoured by wildlife including birds of prey, foxes, woodpeckers
and hares.
ACCESS AND SAFETY:
Access is via the Calderdale Way from Midgley or via a track from Foster
Clough Bridge.
The site is threatened by dumping and motor cycle scrambling.
