 	The valley in the ice and the moraine west of the ice tongue to the west of the terminal lake, as well as the valley to the east of the lake, have deepened perceptibly since my last visit. The ice at the end of the medial tongue has lowered perhaps 6 feet and is now 36.7 ft distant from the boulder used as a benchmark. At the big boulder on the east moraine the ice has lowered perhaps 8 or 10 feet. Actual determination difficult, as covered now with rock debris. Bergschrund extends still clear across the supposed dead part on the south, close to the rock cliff. Crevasses of considerable depth (30-40 ft.) now show on the east part which I once thought dead. We climbed out on the northeast wall and photographed the ice field in the cirque between Arapahoe and "Frozen Lake" cirque. It lies due N of Arapahoe Glacier, from which it is separated by a very narrow, high ridge, very difficult to climb. It is strongly banded, very steep slope, with irregular crevasses in the
