Geomorphological sketch map of the Evans Cove area (Victoria Land, Antarctica)
The morphology of the coastal region between Inexpressible Island and Adélie Cove is here described and mapped. The preliminary geomorphological sketch map in this paper enlarges the southern part of the Northern Foothills that have been previously covered by a published large-scale geomorphological...

The morphology of the coastal region between Inexpressible Island and Adélie Cove is here described and mapped. The preliminary geomorphological sketch map in this paper enlarges the southern part of the Northern Foothills that have been previously covered by a published large-scale geomorphological map (Baroni, 1989). The main aim is to produce a geomorphological map at 1:50,000 scale of the whole of the Foothills, from Inexpressible Island to Campbell Glacier.
