ProssEeR.|  Cretaceous.—Comanche Series of Kansas. L3i 
creek, is 60 feet above river level which indicates that some 20 feet 
of the Red-Beds are above river level at this locality. As near as 
could be determined, the top of the Red-Beds in the Medicine Lodge 
valley is reached near the mouth of Otter creek. On the plateau 
west of Thompson’s creek the Tertiary marl is well shown near the 
top of the prairie. Twenty eight feet below the base of the marl, 
the interval being covered, in the head of a draw, is an excellent 
exposure of the pinkish shaly limestone of the upper Kiowa con- 
taining Jarge numbers of Ostrea, and furnishing an excellent locality 
for collecting specimens of this shell. This locality is one and one 
half miles west of Thompson’s creek and one and one half miles 
north of Medicine Lodge river. Loose on the surface, above the 
Kiowa shales, are brownish sandstones greatly resembling sand- 
stones referred to the Dakota; but no stratum was found in place. 
Along the river valley, above this point, the upper Kiowa shales 
are exposed at intervals in the river bluffs to the forks of the 
Medicine Lodge seven miles west of Belvidere. By the side of the 
river a short distance below the forks is an exposure of the pinkish 
shaly limestone; and west of the forks in the eastern part of Reeder 
township is a steep point, a section of which was measured.

3. Top of hill and all the high country to the north and 
west covered by Tertiary. Base of ledge in place 
115 feet above river level. 
2. Below Tertiary partly covered, abundance of iron- 25—115 
brown sandstone similar to the rock termed Da- 
kota sandstone and probably belonging to that 
formation. In the iower part this sand changes 
into yellowish shale. Base of Dakota? 
1. Ninety feet above river level are shown argillaceous 90— 90 
and calcareous shales of the upper Kiowa contain- 
ing plenty of fossils. In a small draw at this 
locality immense numbers of Gryphaea dilatata 
var. tucwmcartt occur on the surface; the largest 
number of specimens seen anywhere in the Belvi- 
dere region. River level.
