REECE ESCARPMENT. 
This escarpment has not been traced in detail. Itis present at Reece as the most 
conspicuous topographic feature, and was seen at a distance in doing other field 
work between there and Grenola. It runs approximately parallel with the Eureka 
escarpment and about six miles to the west of it, but gradually approaching nearer 
to it southward. Half way between Moline and Grenola it may be seen to the 
north, forming the high hills. It then curves to the north around the head of 
Big Caney and blends with the eastern slope of the Flint Hills west of the creek. 
UPPER LIMIT OF THE CARBONIFEROUS. 
The Cottonwood Falls limestone and the bed of shales above constitute the 
upper member of the Carboniferous. The line of outcrop of this formation has 
not been traced. Prosser* has identified the formation west of Reece, Grenola, 
and Cedarvale. The line shown on the accompanying map as the limit of the 
Carboniferous is therefore only approximately correct. This formation does not 
produce a conspicuous escarpment, and the limestone is masked in the eastern 
slope of the Flint Hills. 
CORRELATION WITH THE PHYSIOGRAPHIC FEATURES IN MISSOURI. at 
The blending of two or more escarpments, or vice versa, the splitting up of 
an escarpment into two or more, as well as the total disappearance of others, 
make it appear that, if the same conditions hold in Missouri that we find in 
Kansas, there can be little certainty that any escarpment will continue across 
the two states. 
The Cherokee lowlands are the equivalent of the Nevada lowlands. The 
Cherokee lowlands extend as a belt across the corner of Kansas. The Nevada 
lowlands are a continuation of this belt into Missouri, where the area narrows to 
a point, according to the mapping by Marbut. 
South of Fort Scott the Pawnee and Oswego escarpments blend. North of . 
the Marmaton river the escarpment thus formed passes into Missouri. I judge 
that it is this escarpment which, after a short curve to the east, continues north- 
ward to the Osage river, and is the one described by Marbut as entering Missouri 
at that place, and named by him the Henrietta escarpment. This escarpment is 
considered by him as the western border of the Nevada lowlands, just as the 
Oswego escarpment is the limit of the Cherokee lowlands. Its course in Mis- 
souri is rather an unexpected one to me, since it seems to cut across to the 
eastern border of the Carboniferous. 
The Erie escarpment has been traced northward by Mr. Bennett to where it 
passes over the state line at the northeast corner of Linn county. It is probable 
that this escarpment continues in a sinuous course in Missouri around the head 
of some streams, and is the same one described by Marbut as the Bethany Falls 
escarpment, which he states enters Missouri in the southern part of Cass county. 
The region between the Henrietta and Bethany Falls escarpments has been called 
by him the Warrensburg platform. To the west of the Bethany Falls escarp- 
ment Marbut describes the Lathrop platform and the Marysville lowlands. It is 
not possible here to give the Kansas equivalents of these belts, since a large area 
intervenes which I have not studied. It would appear, however, that in Kansas 
the escarpments described, or others similar, continue to the Missouri river.
