Geology
Geological setting:
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 youngest moraine and till deposits are near the glacier margin at the mouth of the valley; moraine composition reflects the geology of local rocks, dominantly granite with some sandstone and dolerite
Patterned ground:
Surface weathering or surface features:
Lichen associated with partly weathereed rock surfaces
