the general surface west. From the prevalence of Permian strata, I 
have elsewhere applied the term "Permian mountain" to the ridge. Th:i 
loose flint is of the upper Carboniferous age and some may be Permian. 
The ridge varies from 1.5CO to 1,700 feet elevation above the sea along 
the line of Cowley and Elk, the highest point being near vhe southwest 
corner of Greenwood county, and 1,565 near the southwest corner of 
Elk county. The elevations are closely correct being taken when I 
was in charge of a railroad survey across Kansas in iS/y. 
These flint beds look to a former period when this -^uuntry was at 
least partly covered with water, and in the process of subsiding, the 
gravel beds were deposited, probably by moving currents originating 
from the melting in tlic north of the ice after the close of the Glacial 
period. G. c. upoadhe-xd.
