 This descends first to Stockdale Moor, a site littered with tumuli, hut circles, enclosures and other remnants of ancient habitation.Beyond are the low hills centred on Ponsonby Fell (1,033 ft), not included by Alfred Wainwright in his influential "Pictorial Guide to the Lakeland Fells", but covered by other guidebooks.The north eastern flanks are overlain by drift deposits with the plagioclase-phyric andesite lavas of the Birker Fell Formation beneath.
