It is easy of access from Glacier House, and of great interest to observers. It has its chief source in the Asulkan icefield, which leads to a snow crest or col, known as the Asulkan pass. On the opposite side of the pass a steep descent brings one to the ice stream of the Geikie glacier, the southern overflow of the Illecillewaet icefield. Beyond, lies the steep icefall of the Dawson glacier and Mts. Dawson and Selwyn, over 11,000 feet above sea level.
In the case of the Asulkan glacier, also, observations and measurements were carried on by Messrs. Vaux and Miss Vaux.
On August 12, 1899, a rock in line with the farthest advanced ice of the forefoot was marked. On August 8, 1900, the ice had receded 24 feet. On August 6, 1901, the ice had advanced 36 feet. On July 23, 1906, the ice was again in line with the rock; that is in the same position as in 1899.
Subsequent observations by Miss Vaux show that between August 20, 1909, and July 27, 1912, the ice had retreated 259 feet from the marked rock. During the interval the observations on August 9, 1911, show that the ice had again advanced 51 feet. No measurements made since that date have come to the knowledge of the writer.
