the writer traced this formation from the northern part of Green- 
wood county into Riley county north of the Kansas River. 
There are good exposures of the limestone in the eastern part of 
Chase county on the South Fork of the Cottonwood River and 
its eastern branches. It may be traced up the Cottonwood River 
to Clements; from Strong City to the vicinity of Ellinor, then 
across the divide into the Neosho valley near Dunlap, when it 
follows the bluffs of the river about half the distance to Council 
Grove, then turns northeasterly across the high land of Wabaun- 
see county, passing near Bushong and the heads of the various 
streams in eastern Wabaunsee to Eskridge at the head of Dragoon 
Creek. From Eskridge it continues north on the high land near 
the head of Mission Creek, reaching Mill Creek near Alma. It 
continues northerly across the divide toward Wabaunsee, then 
follows the high bluffs along the south side of the Kansas River 
to Manhattan and extends up the river valley to the vicinity of 
Ogden, about five miles below Fort Riley. Along the entire 
extent of this line which is about one half the distance across the 
state, the formation is clearly marked wherever there are 
exposures, and its distinctive characters are very constant.’

* The author first called attention to the important stratigraphic character of this 
formation and briefly outlined its course across eastern central Kansas in 1894 (see 
Bull. Geol. Soc. Amer., Vol. VI., p. 40, and particularly footnote {). Later Professor 
Haworth has indicated in a general way the outcrop of the Cottonwood Falls limestone 
across the state (Kans. Uniy. Quart., Vol. III., April, 1895, Pl. XXI. and p. 279).
