The hill was quarried for millstone grit from the 16th century until 1955. There were two quarries, one by the northern viewpoint at Windyway producing a blue stone, and the other near the Tegg's Nose summit producing Tegg's Nose Pink. Quarrying was originally by hand, giving a high-quality product used for buildings, gravestones, kerbs, flagstones and cobbles, which was used as far afield as the Isle of Man. Blasting was introduced in the 1930s, producing crushed stone for roads and airfields, and during the Second World War, rock for runways was extracted using pneumatic drills. A collection of historical quarrying equipment is preserved within the Country Park, including a jaw crusher, crane and a stone saw, which was powered by a steam engine. There is evidence of a railway track around the disused summit quarry. There is also evidence of a bomb crater at the bottom of Tegg's Nose, caused by a German bomber during WW2, which can be seen from the summit.
