"% EXPLORATIONS AND FIELD-WORK OF THE SMITH- SONIAN INSTITUTION IN 1919 IXTRODUCTION An important phase of the Institution's work, in carrying out one of its fundamental purposes, the " increase of knowledge," is the scientific exploration by members of the sta.fi of regions in this country and abroad previously imperfectly known to science. The more important of these field researches carried on during 1919 are here described briefly, for the most part by the explorers themselves. Naturally the great war held in abeyance a number of proposed expeditions, some of which it has since been possible to send out on the resumption of a peace status. GEOLOGICAL EXPLORATION IN THE CANADIAN ROCKIES Geological explorations were continued in the Canadian Rocky ^Mountains during" the field season of 1919 with two objects in view: ( ) section of I The discovery of an unmetamorphosed. undisturbed the Upper Cambrian formations north of the Canadian Pacific Railway; and (2) the collection of fossils to determine the various formations and to correlate them with the Tapper Cambrian forma- tions elsewhere. The party going from W^ashington consisted of Dr. and ]\Irs. Charles D. Walcott and Arthur Brown, who has accompanied them for a number of years. Early in July an attempt was made to reach Ghost River northeast of Banfi:', Alberta, but this failed owing to the extensive outbreak of forest fires in that region. In August the party |)roceeded north from Lake Louise over Bow Pass down the Mistaya Creek to the Saskatchewan River, and thence up to the head-waters of the Middle Fork in the area about Glacier Lake, where a wonderfully well preserved Upper Cambrian series of rocks was found that had been cut across in pre-glacial time by a deep east-and-west canyon valley, at the head of which were two beautiful glaciers, which are illustrated by the panoramic view figure I (Frontispiece), and more in detail by figures 5. 7. 8. 9, and 10. Smithsonian Miscellaneous Collections, Vol. 72, No. 1 SMITHSONIAN M ISCELLANEOL'S COLLECTIONS \OL. The character of the mountains about the head-waters of the Middle Fork of the Saskatchewan is ilkistrated by figure 2, where a glacial stream flows out through a deeply eroded valley with high ridges and ])eaks rising in steej:) slopes and cliffs. The position of the camp in Glacier Lake canyon is shown in figure 3. and the outlook to the west toward the glacier from the camp by figure 5, and to the Fig. 2.—View looking up the Middle Fork (Howse River) of the Sas- katchewan River to Howse Pass (5,000') on the Continental Divide. In the distance beyond Howse Pass the peaks of the Van Home Range and Mount Vaux of the Ottertail Range, and on the right and above the Pass Mount Conway, and to the extreme right the eastern ridge of Mount Outram. Locality.—View taken from the upper slope of Survey Peak above Glacier Lake, about 48 miles (76.S km.) northwest of Lake Louise station on the Canadian Pacific Railroad, Alberta, Canada.

'J'he measured geological section begins at the foot of the ridge at the extreme left of figure i, and was measiu-ed in the cliff's and slopes, and thus carried to the side of the Mons glacier shown in NO. I SMITHSONIAN EXPLORATIONS, I9T9 the central portion of figure i, the upper hmit of the section being above the narrow vertical F-shapeci snow bank directly over the glacier. The evenly bedded rocks sloped at an angle of from lo to 20 degrees, westward, which accounts for the great thickness mea- sured, although the elevation above the canyon bed was not more than 3,500 feet.

Walcott, 1919. The glaciers.—The Southeast Lyell Glacier is beautifully shown in figure i. and also in figure 5, and more in detail by figure 6, where it is cascading' over a high clifif. Figure i is a profile view of Lyell Glacier from the Continental Divide on the right to where it abuts ag-ainst the low clifif on the left. In figure 6 the foot of the glacier is shown, along" with large amounts of debris forming the terminal moraine, also the dark mass of broken rock and debris carried on the back of the glacier, which is shown in figures i and 6. A portion of the great snow field from which both Lyell and Mons glaciers flow is shown on the slope of Mons Peak on the left side of figure 5.

Fig. 7. —View of the ice fall of Southeast Lyell Glacier, taken from the surface of the glacier below the fall. The locality is the same as for figure 6. Photograph by Mr. and Mrs. C. D. Walcott, 1919. IMons Glacier is named from Mons Peak, shown in figures 5 and I. It flows over the high clift's (see fig. 8), and creeping down the MISCELLANEOUS 8 SMITHSONIAN COLLECTIONS VOL. 'J2. slope, spreads out in a fan-like form toward its lower end. Seen in profile, this portion of the glacier resembles a great animal sliding down the sides of the broad canyon. The foot of Mons Glacier with the stream flowing from beneath it is illustrated by figure ii. Fig. 8.—View of Mons Peak (10,114') and the upper snow fields of Mons Glacier, also the cascade of the glacier over the cHffs below. The summit of the peak is more than 2 miles {2i-^ km.) back of the glacier, the intervening space being occupied by -a great snow field from which the glacier flows. The locality is about the same as for figures 2 and 5. Photograph by Mr. and Mrs. C. D. Walcott, 1919. These views (figs. 5, 8, 9, 10 and 11 ) illustrate a glacier from its neve at the base of Mons Peak (fig'. 8) to its foot (fig. n ). where the retreating ice is making its stand against the force of the summer sun and wind. Geological section.—The geological section, which is beautifully exposed in the mountain ridge of figure i, is of such interest that it is included in this brief account of the exploration in the vicinity of EXPLORATIONS, I919 NO.
