Geoland
| Dolerite and Beacon Group sediments outcrop over the surface but surficial deposits are scarce; regolith materials may be bedrock largely fragmented by frost |
| action but some sandstone erratic amongst the dolerite suggest some glacial movement of materials; the surface is old as indicated by weathering features |
Descr
| On a prominent remnant bench to the SE of Rougier Hill; the surface has undulating low outcrops of Beacon Group sediments with little regolith cover; dolerite |
| also outcrops in low relief and near the edge of the surrounding escarpment, outcrops are sculptured; where dolerite occurs, a bouldery regolith, possibly |
| felsenmeer, is present |
