THE GEOLOGICAL HISTORY OF SOUTH VICTORIA 
LAND 
By F. Debenham, B.A., B.Sc. (Assistant Geologist 
to the Expedition) 
It is now nearly fifteen years since the first landing was 
made on the mainland of South Victoria Land, since 
which time four scientific expeditions have visited it and 
returned with geological information. This has been, or 
is being, published in the form of reports of a more or 
less technical character. Therefore it seems advisable 
that an attempt should be made to condense this informa- 
tion into a popular narrative of what actual changes 
that area has undergone in past time, so far as they are 
known. 
The tale must necessarily be incomplete, for the 
difficulties confronting geological investigation in those 
regions are naturally considerable, but enough has been 
done to warrant a preliminary interpretation of the 
known facts. 
South Victoria Land at the present day is marked 
on the map as a strip of coast running in a southerly 
direction from Cape Adare (Lat. 71°) and merging into 
King Edward VII Plateau in the region of the Beardmore 
Glacier (Lat. 83^-85°). As appears in the physiographic
