Geoland
| The rock outcrop on the ridge is granitic and is fractured and jonted to 25cm; fine material fills cracks between the rocks and may be wind blown; the surface has |
| probably been overtopped by late glacial ice and there is some argillite incorporated in the regolith indicating addition of till |
