Geology

Geological setting:

Glacial deposits in the area are formed from a complex interaction of advances from the Taylor Glacier with nearby alpine glaciers; granitic rocks are common and intruded by dolerite and dyke rocks but there are also numerous small volcanic cones which post-date glacial episodes; some shallow gullies mark the sites of ephemeral past water flows from thaw waters from the Marr Glacier; occasional surface salt precipitations may be due to evaporation of excess water
