ANTARCTIC ADVENTURE AND RESEARCH 



there were lake-filled hollows which seemed in general 

 to be due to the melting of extremely ancient masses 

 of ice, once covered by the moraine. These were com- 

 mon on the west side of the Koettlitz Glacier, where 

 Alph Lake was nearly a mile long, and is in part still 

 walled in by ancient ice. Others were due to moraines 

 which blocked the outlet of the valley, as, for instance, 

 below the Garwood Glacier, where the lake was two 

 miles long. Lake Bonney below the Taylor Glacier

is also two miles long. It seemed many feet deep and 

 full of algae, but we had not time to cut through the 

 ice surface and investigate it more fully. There ap- 

 pears to be a rock sill between Lake Bonney and the 

 sea, for the defile at its eastern end is over one hundred 

 feet above the sea (see Figure 13). 



David and Priestley describe at length many of the 

 small lakes near Cape Royds (see Figure 8). These 

 were investigated during the winter by means of 

 trenches. Most of them lay in the hollows in a long
