ANTARCTIC ADVENTURE AND RESEARCH 



porphyry, ''Shap granite" and a few bowlders resem- 

 bling troctolite. A few small striae were visible on 

 some bowlders. The latter varied in size from four 

 feet in diameter down to fine powder. At the side 

 were pools filled with yellowish water. Here was one 

 of the few occurrences of fine silt which I observed. 



Other heaps occurred close by, of irregular shape and 

 not quite so high. About seventy yards away to the 

 west appeared another ridge and between were a few 

 big blocks. Possibly there was moraine between cov- 

 ered by the ice, but the lack of debris on other glaciers 

 makes me doubt it. The southern margin of the glacier 

 was intersected by numerous small stream.s. Here on 

 January 28th, 191 1, the main stream was two feet wide 

 and about one inch deep. There was, however, much 

 greater flow along the northern bank of the glacier. 



There was an interesting zoning in the character of 

 the debris covering the valley slopes hereabout. Next 

 to the glacier was a belt at a low angle consisting of 

 clayey silt containing stones one or two inches long. 

 A hundred yards south this deposit had become a sort 

 of gravel meal which is very characteristic of Ant- 

 arctic surfaces. Then came a belt of sharp shingle or 

 angular gravel, each piece being about two inches long 

 with very little powder visible. Above this (to the 

 south) were the coarser blocks, which became fairly 

 continuous at about four hundred yards from the gla- 

 cier edge. Here I was about two hundred feet above 

 the ice. Just below the granite erratics, which were 

 up to four feet in length, though mostly less than one 

 foot, was a large patch of moss about sixty feet long
