Geoland
| The valley floor moraines are formed by northward down-valley retreat of ice from Long Valley; moraine patterns are complicated by local ice stranding on the |
| valley sides; the oldest valley floor moraine lies in a strip in the centre of the valley; the till composition reflects the geology of local rocks, dominantly granite |
| with some sandstone and dolerite |
