Of Carp Lake, which was once much larger than at present. 
f rha dip oT the strata toward the north has created a great 
cliff or escarpment, which is continually weathering away, 
producing a talus slope at its foot (fig. 24). This cliff 
extends west and west-southwest across T* 51 B. H. 43 V/., 
a distance of about 10 km. I*c varies from point to point 
alo r the range as to elevation of summit, height of escarp¬ 
ment and width of talus slope. At. one point opposite Carp 
lake the talus descends into the luko; hut at most points 
there is a fringe of forest between the foot of the talus 
and flood plain of the river, as shown in fig. 24. In sec. 
14, there is a depression in the cliff where the escarpment 
has entirely disappeared leaving a saddle across the range. 
The same thing, though less marked, occurs about a mile 
west in sec. 15, and in varying degrees at other points along 
the range, making it possible at such places to descend into 
the valley without difficulty. Where a saddle i3 sufficiently 
low, as in sec. 14, the talus is almost entirely covered by 
soil washed from above, and the fringe of forest, from below 
may extend clear across the depression. In sec. 15. (fig. 
25} this process has not gone so far. There is still a rock 
faco varying from 3 to 5 m. high. The relation between the 
various physiographic features as thoy appear at different 
points along the range is shown in fig. 26.
