^vard. I'requently on Clifty Creek a stratum of stoiie below the Waldron 

 shale is seen which very much resembles the hydraulic beds of Wabash 

 County, both in appearance and jointed structure. The laminated shale 

 ■of Wabash is duplicated by some of the more argillaceous shales of 

 Clifty Creek. The Wabash Valley and Laurel- Waldron unconformities 

 seem to be of the same horizon and lend color to the inference that the 

 <iuarry stone of Wabash County and the Waldron shale are of the 

 ^ame age. 



The Valley of the Lom er Tippecanoe River. 

 Fred J. Breeze. 



[Abstract.] 

 The Tippecanoe River deserves far more attention from the geographer 

 and geologist thaji has ever been given to it. A careful study of this 

 stream will shed light upon some of the problems of glacial phenomena, 

 and will doubtless yield something of interest concerning stream and val- 

 ley development. Believing this, tlie writer has begun a somewhat sys- 

 tematic study of tliis river. Several days of the last throe months have 

 been devoted to the necessary field work in the preparation of a map of

the lower part of the Tippecanoe Valley. This map shows the mean- 

 ders of the .stream and of its valley, and is presented at this time with the 

 hope that it may be some little contribution to the geography and geology 

 ■of Indiana. 



By Lower Tippecanoe is meant that part of the river from the point 

 where it leaves the region of the Glacial Lake Kankakee to its mouth.
