Geoland
Moraines on elevated surfaces to the south of Koerwitz Glacier show distinct age differences between the lower and higher altitude surfaces; the younger |
moraines clearly show signs of a re-advance of ice from the north; granites predominates but some dolerite, schist and dark metavolcanic rocks are present; this |
surface appears less weathered than for site 281 |
