20 TOPOGRAPHIC DEVELOPMENT OF KLAMATH MOUNTAINS. Lbitll.196. 
where, in the broad crest of the range, it joins the Klamath plain of 
the western slope. The even-crested divide between Cache Creek on 
the one hand and Stony and Bear creeks on the other carries the Bell- 
spring peneplain eastward into the Sacramento Valley, while to the 
northwest, as seen from the summit of Bartlett Mountain, it rises to 
the flat, snow-covered (October 11, 1900) crest, Snow Mountain, at an 
elevation of about 7,000 feet, forming the line between Lake and 
Colusa counties. PI. VI, reproduced from a photograph by Mr. Burt 
Cole, illustrates the general flatness of the summit region (Klamath 
peneplain) as seen from a distance at a somewhat lower level. To the 
left of this view, beyond the crest of the range, is "Ocean View," at an 
elevation of 0,700 feet, from which the outlook to the south is given 
in PI. VII. Snow Mountain (summit, 7,040 feet) and Mount St. John 
rise a little above the flat portion of the Klamath peneplain. 
Beyond Bartlett Springs, 20 miles toward Williams, the stage road 
crosses the Bear Creek divide. A short distance north of the stage 
station, at an elevation of 2,700 feet, it affords an extensive view of 
the peneplain rising northwest to the crest of the range, and to the 
east, northeast, and north the even-crested ridges of the Coast Range 
foothills stretch away for miles, forming the divide between Bear 
Creek and Stony Creek on the west and the broad alluvial plain of 
the Sacramento on the east. 
The first crest crossed east of Leesville among the Bear Creek hills 
is 2,250 feet in altitude, and beyond Antelope Valley the front ridge, 
a few miles southeast of Vernado, overlooking the great plain of the 
Sacramento, has an altitude of 2,000 feet. To the southwest from the 
front ridge the view across these Bear Creek hills and a series of 
even-crested divides shows a remarkable development of the Bell- 
spring peneplain (PI. V, B). 
Bally Mountain, a few miles southeast of the stage station, on the 
divide between Cache and Bear creeks, is a mass rising prominently 
above the peneplain about its base, and in places on the mountain 
slopes, as seen from a distance northeast, there appear to be traces 
of planation above the general peneplain, but the ascent of Bally 
Mountain could not be made in order to study the matter. 
The Bellspring peneplain ends abruptly on the crest of the foothills 
along the western border of the Sacramento Valley plain in Colusa 
County. The bold front facing east has an altitude of nearly 2,000 
feet, and extends southward more or less continuously through Yolo 
County into Solano County. South of the deep gap cut in this front 
ridge by Putos Creek the crest rises from 2,500 to 2,900 feet. 
To the northward from Colusa County this front extends with 
decreasing height into Glenn County, and the Bellspring peneplain is 
finally brought down to the level of the later plain of the Sacramento 
Valley. Although the plateau front sinks northward, the plateau 
surface for some distance west of the front rises in that direction
