On terminal moraine on east bank of river, rock No. 1, marked:—
"A.C.C., No. 1, July 15, 1906.
Nearest ice 27½ft."
At highest point of moraine, at a distance of 79.3 feet southerly from rock No. 1, took photograph of most advanced ice.
(See Plate)
Rock No. 2, on same moraine, marked:—
"A.C.C., No. 2, July 15th, 1906, 33.6 ft."
Took photograph of front of glacier from this rock.
Mr. George Vaux renewed the marks placed by Miss Vaux in August, 1901.
The marks were:—"V|X. Aug., 1901."
These were placed an west face of a rib of rock on the east side of the river, as nearly as possible at right angles to the line of the most advanced ice.
Took photograph of front of glacier at a point along rock rib, 6½ feet nearer to the ice. Marked this point "V. P."
