ADAMS: PHYSIOGRAPHY OF SOUTHEASTERN KANSAS. IOI 
THE REECE ESCARPMENT. 
This escarpment has not been traced in detail. It is 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 Cana 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 for- 
mation does not produce a conspicuous escarpment, and the lime- 
stone is masked in the eastern slope of the Flint Hills. 
CORRELATION WITH THE PHYSIOGRAPHIC FEATURES IN MISSOURI. 
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 asa 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 northward 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,
