160 KANSAS UNIVERSITY QUARTERLY. 
and Elk counties are in the Flint Hills, the crest of which is near 
the Cowley—Chautauqua and Elk county line. 
For the purpose of studying the stratigraphy af the southern 
Flint Hills and determining their geological formations, two sec- 
tions were followed from the east across them. ‘The northern 
section is along the line of the Atchison, Topeka & Santa Fe rail 
road from Moline, Elk county, through Grenola, Grand Summit 
and Cambridge to Grouse creek, Cowley county. The southern 
one is along the Missouri Pacific railroad from the vicinity of Cedar 
Vale, Chautauqua county, through Hooser, Dexter and Eaton to 
Winfield, Cowley county. 
SECTION FROM GRENOLA TO GRAND SUMMIT. 
The Grand Summit section is, perhaps, the best known Permian 
section of southern Kansas. This is due in part to the abundant 
fossils found in the railroad cut east of Grand Summit station. A 
section of the eastern side of the Flint: Hills, in this region, was 
described by Prof. Broadhead in 1882,! and the writer’s attention 
was first directed to the locality by the fine collection of Permian 
and Carboniferous fossils from it in the Geological Museum in the 
University of Kansas. Mr. Geo. I. Adams has also described in a 
somewhat general way the section along the line of this railroad 
through Moline, Grenola and Cambridge to Winfield. * 
In the northern part of Moline, on the bank of the Wild Cat 
creek, are iron-brown shaly limestones containing large numbers of 
Fusulina cylindrica Fischer and other fossils. On the hill to the 
northwest of the city is quite a thickness of drab to buff sandy 
shales, that contain but few fossils. These are capped by a thin, 
brownish to yellowish limestone. The rocks in the vicinity of 
Moline probably belong in the Wabaunsee formation. 
Grenola is,situated in the valley of Big Caney creek, Greenfield 
township, in the western part of Elk county. The railroad cut, 
immediately east of Grand Summit station, is five miles north of 
west from the bluish shales on the bank of the Big Caney creek 
just west of Grenola which form the base of the following section 
from the creek to the cut east of Grand Summit: 
No. Feet. 
28. Top of railroad cut, east of Grand Summit, yellowish 15==407 
to bluish shales and shaly limestones in which fossils 
are very abundant. An excellent locality for collect- 
ing.
