SOME OBSERVATIONS ON THE TOPOGRAPHY 

 OF ATHENS AND VICINITY. 



By C. H. Stearns. 



South-eastern Ohio presents some very complicated 

 problems to the topographical geologist. Among these 

 Complications, those of Athens county are notable and 

 of peculiar interest ; for through this section flows the, 

 Hocking ( Hockhocking ) river, along a valley now many 

 times the width of the stream, and through glacial drift 

 gravels of immense thickness, and along the hill-tops, 

 close to Athens township, are evidences of an ancient, 

 pre-glacial river which flowed in quite a different direct- 

 ion than that of the present Hocking, viz., to the south- 

 west, on, we believe, to the Ohio, by w^ay of the Sciota 

 River. 



Let us first consider, briefly, the course of the Hock- 

 ing river, especial from Salina, six miles above Athens, 

 to a point somewhat below^ the town.
