Purpose: To examine sedimentary rocks and structures in the Carboniferous age rocks of the Bowland sub-Basin (part of the more extensive, Craven Basin) The rocks vary with shales, mudstone, siltstones, limestones and sandstone belonging to the Craven and Millstone Grit Groups all being exposed. Fossils are abundant in some beds and there is also evidence of mining for galena and sphalerite. The rocks were deformed during the Variscan Orogeny and lie within the Ribblesdale Fold belt, a series of NE -SW trending anticlines.
