inches in July, and 21i inches in August. Days with blizzard numbered five in June, four in July, and nine in AUgust. Consequently the original ambitious plan of surveying the whole ice cap was restricted to the southeastern lobe. The first two traverses (Nos. 1 and 2) were made from Camp A to the southeast and to the southwest. Hans R8thlisberger, of the Swiss Foundation for Alpine Research, took the levels while l read the gravit y meter. His alpine experience was very helpful to me in learning to overcome difficulties in the ablation zone: the first traverse ended ~ifhenl stepped up to my waist in a stream filled with slush. Pulling a small hand-sledge loaded with the gravit y meter and other gear, l left Camp A on July 19 to continue work at Camp A2, a subsidiary camp, which had been first set up on the ice edge and later moved to the south shore of Generator Lake. ~lidsummer was approaching and the ice cap was covered ~i1th rivers which made travel difficult. A few miles from the ice edge l cached the sledge near a shallow lake, about a third of a mile in diameter, filled vvith slush and water. The following day John Haller, the mechanical engineer of the expedition, and l returned for the sledge. We found that the slush lake had drained away and that the rivers which had been feeding it were pouring into great holes and crevasses. Shortly after arriving at Camp A2 l began a gravit y survey of the southernmost part of the ice cap. This was suggested by R.P. Goldthwait, the geomorphologist of the expedition, who predicted a valley beneath this part of the ice cap from a study of the local topography. He believed that the valley ran under the ice from Generator Lake to the north end of Flyway Lake. Three traverses (Nos. 3, 4, and 5) were made across this area and the results confirmed that this valley existed and showed that it followed a similar course to that predicted by Dr. Goldthwait. Two more traverses completed the gravit y survey. One extended north from Camp A (No. 6); the other lay roughly east and west (No. 7), near Gee Lake. Towards the middle of the latter traverse a broad depression of about 200 feet deep was shown to lie beneath the bottom of the iee cap. This is presumably a continuation of the valley of Gee Lake. The three long traverses radiating from Camp A show that the ground beneath the middle of the southeastern lobe is about 100 feet lower than the ground at the ice edge. Vfuether this is a natural depression or whether some compensation due to isostasy has occurred is not known. The greatest computed thickness of ice is 1,550 feet, three miles north of Camp A.
