creek and the Neosho near Laneville. East of the Neosho it 
passes McCune to the south, and runs up Lightning Creek crossing 
it near its head, from which place it follows a sinuous line north of | 
Girard, west of Englevale and east of Pawnee station to Godfrey, 
where it blends with the Oswego escarpment. 
THE ALTAMONT ESCARPMENT. 
The next limestone formation is the Altamont.* It is found 
at the top of the escarpment which passing east of Altamont 
and extending to the south, runs just east of Edna and into the 
Territory, becoming very prominent there. Tracing the systems to 
the north they are found to pass from Altamont north to Parsons, 
at which place they produce no escarpment. Along the west bluff 
of the Neosho they are again important, but the escarpment fades 
out around St. Paul in the Neosho bottoms. To the northeast, 
past Brazilton, Farlington and Hiattsville, there is a prominent 
escarpment but it is largely due to the thick sandstone beds which 
produce the flagging stone quarried at many places. In the valley 
of the Marmaton the escarpment disappears but 1s again found 
further north. ; 
: THE ERIE ESCARPMENT. 
This escarpment is most prominent along the Marmaton river 
near Uniontown, from which place it runs to thé northeast, passing 
out of the state east of La Cygne, according to Mr. Bennett who 
is familiar with that region. [following it to the south it passes 
east of Savonsburg nearly to Walnut, thence westward north of 
Erie, where it crosses the Neosho river. It is produced by three 
limestone systems called collectively the Erie formation. + 
They are quite closely associated along the course already 
described and the escarpment is one of the most prominent in the 
southeastern portion of the state. South of the Neosho, however, 
the systems separate, due to the thickening of the intervening 
shale beds, and the lines of their outcrops diverge. 
THE HERTHA ESCARPMENT. 
The lower member trends to the east around the head of a creek 
to Hertha. An outlying area is found at South Mound. From 
Hertha the escarpment runs westward crossing Labette creek 
south of Galesburg and follows its west bluff for a considerable 
distance. It is prominent at a few places on Little Labette Creek 
and finally terminates in the mounds west of Altamont.
