62 TOPOGRAPHIC DEVELOPMENT OF KLAMATH MOUNTAINS, [bull. 196. 
3. The differential uplifting, always in favor of the crest of the 
range, across which the Klamath River has long continued to cut its 
way, has given the Klamath River and headwaters of other streams 
relatively not only much greater cutting power, so far as grade is con- 
cerned, but a larger amount of work to do, and for this reason their 
canyons are more profound and the topographic cycle is less advanced 
than in the Coast Range, where the streams, having greater volume, 
reduced the country more rapidly. 
Notwithstanding minor differences, the topographic continuity of 
the Coast Range and Klamath Mountains is pronounced. Of the two 
the Klamath Mountains are the older, although in a measure, for 
reasons given above, less advanced in the cycle of erosion than the 
Coast Range.
