Rh ing a pure white peak from surrounding fields of snow. Every- where confluent glaciers sent their broken masses to the ice-rivers below. Jagged rock-walls, too steep to sustain a weight of snow, broke the monotony of white by their black outcrops. Peaks, glaciers, snow-fields, ridges and valleys reached to the furthermost distance, which was lost in a roll of billowy clouds."

Dawson Glacier—Name: In relation to Mt. Dawson.

Altitude: 5.500 to 10,000 feet.

Location: Between Mts. Dawson and Fox; falls steeply to join the Geikie Glacier, presenting a much shrunken snout covered with debris. The dry glacier is much crevassed. Near the lower extremity, it unites with the Donkin Glacier. A special feature is the long, symmetrical lines of its two lateral moraines, which like well-built levees confine its flow. Along the crest of these moraines are well-worn paths made by goats, which may frequently be seen trooping in single file to and from their feeding grounds.

Deville Mt.—Name changed to Selwyn (see Mt. Selwvyn).

Deville Glacier and Névé—Name: In relation to Mt. Deville (Selwyn).

Altitude: 5,300—8,300 feet.

Location: Between Mts. Topham and Selwyn and extending southerly along the great escarpment of the Selkirks Summit to Grand Glaciers.

First traversed by Messrs. Huber, Topham and Forster in 1890.

Route: Reached from Glacier (1) via Glacier Circle and Bishop's Glacier; (2) from Beaver River Valley via Glacier Circle and Deville Glacier. This glacier is of extreme interest, presenting a perfect example of the Forbes dirt bands on a large scale. Soon after leaving the névé the glacier flows over a precipitous ledge and is broken into wide crevasses extending the entire width of the flow. The enormous shove from behind brings the ice together again, closing these great cracks; but, owing to the more rapid flow in the centre of the ice-river, they now form circular joins where the dust blown over the ice, collects and gives the dry glacier a graceful and fan-shaped appearance, outlined by dark circles. This is seen to particular advantage from the summit of Mt. Fox. The névé is about three miles long and has several arms extending westward, in all about six square miles. It connects by easy snow-passes with Bishop's Glacier and Black Glacier. The southern extremity overflows to the Grand Glaciers. The rocky rim along its eastern margin, with Mt. Topham at the northern extremity and Beaver Overlook at the southern, furnishes comprehensive view-points for the Beaver River Valley, the Spillimacheen Mountains, Bald Mt. and the Dogtooth Range.

The Dome—Name: By Messrs. Abbott, Fay and Thompson on account of its contour.

Altitude: 9,029 feet.

Location: A peak of the western escarpment of the Asulkan Valley, between Castor and The Rampart.

First Ascent: By Messrs. H. B. Dixon, A. Michael. C. L. Noyes, C. E. Fay, J. R. Van Derlip, with guide Peter Sarbach, in 1897.

Route: (1) Reached from Glacier, via Mt. Abbott, skirting Mt. Afton and traversing the slopes of the Rampart to the foot of the
