Geology

Geological setting:

Rocks of this area include granites and a series of metsedimentary rocks; at Mt Rigby the rocks are mainly granites but the landscape has an old appearance on the higher surfaces which have been inundated by later ice advances, most probably from an expanded and grounded; moraine alongside glacial ice is very recent
