SMITHSONIAN EXPLORATIONS, I918 



Figure 7 pictures Bow Lake as seen from the eastern slope of 

 Mount Thomson. This view over the lake from the north shows the 

 ridges on the right formed of Middle Cambrian limestones, while far 

 away in the distance the snow-clad summit of Mount Hector is 

 buried in the clouds. In figure 8 is shown a nearer view of Mount 

 Molar, a beautiful example of horizontally bedded limestones, illus- 

 trating the manner in which the hard, evenly bedded limestones 

 erode into domes and broad cvlindrical masses.

 of Bow Lake. Photograph by Walcott, 1918. 



There was fine trout-fishing at the lower end of Bow Lake, and we 

 met with both deer and grizzlv bear in the somewhat open valley 

 at the head of the lake (fig. 9). 



The snow-fields from which Bow Cdacier flows are on the Con- 

 tinental Divide between the Bow A'alley and the L'p])er Yoho \'alley. 

 The glacier fiows down a gentle slope for a mile or more, and then 

 breaks over a high clilT, as shown in figure 10. There are beautiful 

 cam])ing grotmds on the shores of both Blector and B)OW lakes, 

 especially the latter. From one of these camps (fig. 11), geological 

 sections were measured of the Cambrian rocks on the eastern slope 

 of Mount Thomson.
