This panorama shows the striation of these cliffs by the ice in past years, when the glacier filled up the trough as high as the upper line of dense forest. The grooving and fluting of the rock over which the ice grinds is well shown by the uncovered portion where the fragments fallen from the séracs above are lying. On the extreme right may be seen the nunatak, which spilts the icefall into two parts (Refer to map opp. page 152, Vol. I., No. I, Can, Alpine Journal). The appearance of the lateral moraine that has been left standing around this nunatak and its position with regard to the timber growing thereon, suggest strongly an advance of the glacier subsequent to the growth of the timber on the nunatak.
For Advance or Retreat.
To obtain some idea of the movement of the ice forefoot with reference to its position in the valley, measurements were made from Rocks Nos. 1 and 2, marked in July, 1906; and, also, from the "Sherzer" rock marked in August, 1904. The measurements were to the nearest ice and the results are not very satisfactory, owing to a considerable change in the structure of the forefoot during the twelve months elapsed since July, 1906.
| Point Measured From | 1904 | 1906 | 1907 |
| Rock No. 1, left side | 27.5 feet | 35.8 feet | |
| Rock No. 2, left side | 33.6 feet“ | 43.8 feet“ | |
| Sherzer Rock, right side | 79.4 feet | 79.6 feet“ | 123.0 feet“ |
The above measurements would point to a slight retreat. The greatest shrinkage appears to have taken place on the right side, indicating the withdrawal of
