_ the Columbia on the west side, and the Flathead River in the 
mountains, from an altitude of 1000 to upwards of 4200 feet 
above the sea. ey are in some places very marked, and 
appear as a succession of steps from the bed of the river to the 
level of the plain above, often in sight for miles, and running 
horizontally along either side. ‘The tread of the step is of 
greater or lesser width, the rise nearly always abrupt and well 
marked. They were very decided in the valley of Bow River 
at the base of the mountains, where they appeared cut with 
mathematical accuracy.

won Belly River at about the same altitude as on 
Bow River at the site of Bow Fort, namely, 4000 feet above the 
sea, although eighty-seven miles (geographical) in a direct line 
S.S.E. from it. From this point the route of the party may be 
traced on the plan attached to this report. The plan does not 
include the country to the northward, which has no connection 
with the passes reported upon. I have, however, the whole 
country mapped on a smaller scale. ; 
The bed and sides of this river are rocky, the strata of hard 
gray sandstone, much inclined, and the current obstructed in 
places by immense granite boulders. We found no difficulty in 
- crossing, the water though running swiftly, being not deeper 
than three feet, and about twenty-five yards across. 
Looking through the gap in the near range through which the 
river issues, I saw a conspicuously dome-shaped mouitain. It 
fterwards proved to be when séen from the plains, and also from 
the top of a mountain in the Kootanie pass, the highest and 
almost only peak rising above the others in this part of the 
mountains. After the clistingraish 6a British naturalist, I named 
it “Gould’s Dome.” The gap through which I had seen this 
mountain was in the eastern or near range, of very regular form, 
extending with the exception of this gap, for a distance of five 
and twenty miles without break. The crest of the range was 0! 
so regular a form, that no point could be selected as a peax, I 
_ therefore gave the whole the name of “ Livingston’s Range;” 1t 
is a very marked feature when seen from the forks of Belly
