Spec. 701 - Beroë Calliaris & see pp- 33-35 of this book Feb., 1917-Radcliffe Island-i.e. the first and largest of the three islands forming south side of entrance to the fjord-is of horrible green containing many granitic veins. Much gravel mixed with small cobbles occurs on the island. The exposed rock ledges are well groo- ed and striated glacially. Movement of ice apparently from northeast. The proportion of rock exposed is less than on Storn Island. More gravel. 9 Feb. Visited Brother John's Place. Ice of lake proves some advance of nor- hern portion of glacier during the winter. Ten to thirty feet in front of the glacier a ridge of lake ice has been raised roughly parallel to the front of the glacier. Where largest this ridge is approximately ten feet high with sides sloping at 45°. This would indicate a crude estimate of 8 feet of forward motion in the past 100 days, or about 1in. per day. The ice is broken at the top of the arch. It rose from the surface of the lake and left an open space. Roof is per- haps 15 inches thick. Mac tells me
