their base as we aproach Otter creek, near the mouth of which is 
the top of the Red-Beds. On the south side of the Medicine Lodge 
river the Comanche series extends farthest south up the Otter 
ereek, and not far from the mouth of the creek, in a draw crossed 
by the railroad and a short distance north of the Blue Cut, the top 
of the Cheyenne sandstone is exposed together with the Champion 
shell-bed. This cut and the Blue Cut mound, three or more miles 
southwest of Belvidere, have already been mentioned as described by 
Professors Cragin and Hill. 
Section of the Blue Cut and Mound. 
No. Feet. 
6. On the summit of the mound, or “nipple,” loose 
pieces of Tertiary marl. 
5. Partly covered slope. Large blocks of brown and 20—151 
iron colored sandstone occur, some apparently 
coming from a stratum in place.t 
4. Thin limestone containing Gryphaea and other 45—131 
fossils. The slope of the mound from the base of 
the brownish sandstone to the top of the railroad 
cut is mostly covered. The section of Gould and 
: Hill gives 48 feet. | 
3. At top of railroad cut is a shaly Ostrea limestone of 11-8—86 
pinkish color, No. 18 of Hill and Gould’s section. 
Lower are yellowish shales and shaly limestones. 
2. Dark gray to blackish shaly limestone perhaps 223—744 
weathering to a pinkish color. Bluish-black 
shale in the lower part of the railroad cut in 
which are three prominent bluish limestone 
‘layers containing abundant specimens of Ostrea. 
Base of railroad cut. 
1. From the railroad cut to the top of the Cheyenne 52—52 
sandstone, which is exposed in a draw north of 
the cut, the intervening space being mostly 
covered, there is a barometrical difference in alti- 
tude of 52 feet. 
1 In describing this section Professor Hill gives 20 feet of black ferruginous 
sandstone which is referred doubtfully to the Dakota. Thirty rods north of the 
line of his section he states that the ‘‘Tertiary rests directly on the Belvidere 
shales. SUA having been eroded’ (American Journal Science, 3rd_ series,
