The sandstone noted above, with yellowish and grayish color also 
shows streaks of other colors as reddish, brown, etc., and thus in 
its lithological character closely resembles the Cheyenne sandstone 
while it also occurs at a similar stratigraphic position, between the 
Red-Beds and the base of the Kiowa. About three miles northwest 
of the locality just described, on the divide between the east and west 
forks of the Kast Branch of Bear creek the Comanche series was 
again measured. This locality is on section 3, township 32 s., range 
23 w., and eight miles northwest of the city of Ashland. 
Section between the Forks of the Hast Branch of Bear creek.

6. Calecareous grit belonging to the Tertiary. From 105—424 
the top of the high prairie on the divide, to the 
base of the Tertiary 105 feet. 
5. Yellowish sandy shales which are fossiliferous and 32—319 
change into blackish shales in the lower part. 32 
feet. 
4. Sandstone and yellow arenaceous shales forming a 5—287 
conspicuous division of this formation and here 
similar in lithological appearance to the one de- 
scribed in the Amphitheatre section on Bluff 
creek; but occurring in the present section 25 
feet higher in the formation. 5 feet. 
Mainly yellowish shales—in places somewhat arena- 60—282 
ceous. 60 feet. 
2. Thin sandstone stratum. Yellowish sandy shales 42—222 
which in the lower part are black fine argilla- 
ceous shales containing abundant crystais of 
selenite some of which are the twinned form. 42 
feet—base of Kiowa. 
. Top of Red-Beds. Red shales and sandstones for 180—180 
180 feet to the creek level at forks of East 
Branch Bear creek. 
One of the most interesting places to study, in the central part 
of Clark county is a canyon near the upper part of the West Branch 
Bear creek. Near the northwest fork of the creek is a narrow 
cafion with steep rocky sides, composed entirely of coarse brown-
