Geoland
the rocks of the area are granodiorites that have been cut with lamprophyre dykes and form a strongly undulating ridge and gully topography as a result of ice |
over riding from down-valley and up-valley glaciations and to a lesser extent, subaerial weathering; subsequent to glaciation, the terrain has been subjected to |
drowning and emergence from fluctuating lake levels from Lake Vanda with some sorting or resorting of surficial materials |
