corner of Tippecanoe County. From this angle there also extends a 
broken chain of mounds northeast to near Dayton. Another well defined 
ridge, from the low crest of which rise many mounds, extends southeast 
from near Independence, on the Wabash, to Darlington, Montgomery 
County. Parallel with it on its eastern slope lies the belt of bowlders well 
known to Indiana geologists. Shorter and less conspicuous ridges extend 
east and west, at distances of about three miles apart, across the part. 
of Tippecanoe County further south. Two or three such ridges traverse 
the northern part of Fountain County. Many mounds dot the region in 
no discernible relation to each other or to the chains and ridges. All 
these ridges and mounds of gravel have the regular stratification of water- 
laid deposits. 
The drainage of the region is interesting and peculiar. The Wabash 
crosses Tippecanoe County through an immense deposit of gravel extend- 
ing from the eastern to the western boundary of the county, having a 
width of from one to six miles and from two to three hundred feet deep. 
Between Warren and Fountain counties, from the western side of Tippe- 
canoe to Portland, Fountain County, the stream runs on bedrock in a 
valley about a mile wide and one to two hundred feet deep. The smaller 
streams of Tippecanoe County, south of the Wabash, converge from the 
eastern and southern more elevated clay plains and the line on the south- 
west formed by the Darlington-Independence ridge. West of this the 
streams run west into the Wabash. The unusual course of the Wea Creek 
and of Coal Creek should be noticed particularly, the course of the former, 
forming a great semicircle, the latter having a course with an abrupt 
bend in it strangely similar to that of the Wabash. It should be noted 
also that the streams just over the south and southwest divides of the 
Wea basin in several places have their sources very near those of this 
basin, and in all such places there is a sag or connecting valley across 
the divide. Notice, for examples, the heads of South Flint and North 
Shawnee, Little Wea and Big Shawnee, Big Wea and Coal creeks. Note 
also the nearness of the northward-flowing tributary of Shawnee to the 
elbow in Coal Creek. 
The foregoing statement of topographic facts is made in view of a 
possible solution of some problems that are suggested by them. 
Mr. Chamberlain has called this a region of readjustment in glacial 
movement, and this statement seems to be the key to the solution of the 
problems that present themselves. When the last great North Ameri-
