 Several greenstone knapping sites have been found below the main peak, and following the strike of the tuff exploited at nearby Pike O'Stickle in the neolithic period.The sites on Pike O'Stickle have been well described as the Langdale axe industry, but they have been found to be much more widespread than originally thought.The rock was roughly shaped on site, and then traded across the country, where the final polishing could be undertaken.
