 higher mountain slopes. A nearer view of Peyto Glacier is given in 

 figure 15. and figure i6 shows Pyramid Peak, one of the peaks en- 

 countered in the Mistaya River Canyon. 



The broad canyon valleys that unite at the head waters of the Sas- 

 katchewan River (fig. 17) are all carved by erosion out of the same 

 type of Cambrian rocks as those exposed in the vicinity of Bow 

 Lake, and also in the P)Ow \'alley south of Lake Louise Station.

-Skinning out mountain sheep shot above head of Sawback Lake 

 on September 21. Photograph by Walcott, 1918. 



At the close of the season a fine pair of mountain sheep, a black 

 bear, one mule deer, a mountain goat, and a wolverine were col- 

 lected, the skins and skulls being shipped to the National Museum. 

 At a salt-lick on the west branch of the Saskatchewan River many 

 goats were seen. Some of them in an attempt to escape observation 

 were forced to pass over a sharp ridge directly in front of where 

 Mrs. Walcott was sitting, with the result that she obtained an unusual 

 ])hotograph of five of them (fig. 18) as they were clamliering over 

 the apex of the ridge.
