GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



leave little room for doubt that the basin of Lake Huron determined a southerly 

 movement of the ice current, and thereby rendered collateral aid to the Michigan 

 Basin in directing the broad stream east of the unglaciated island.' 



A movement to the east of south from the region north of Lake Huron 

 is also shown by strlse to have taken place at some time during the Grlacial 

 epoch, there being striae with southeastward bearing south of Greorgian 

 Bay and southeast of Lake Huron, while the majority of those north of 

 Lake Huron bear southward. The evidence from striae, therefore, supports 

 rather than antagonizes the evidence from bowlders that there were south- 

 Avard movements over western Ohio at some time during the Glacial 

 epoch. The later movements, however, seem to have been southwestward 

 through the Lake Erie Basin, and thence southward into central Ohio, 

 with lateral movement toward the southeast on the eastern side of the 

 Scioto lobe. 



In the following table are an-anged all the published as well as the 

 unpublished observations of striae pertaining to the Scioto lobe so far as 

 known to the writer. The striae all appear on the map of the Scioto lobe 

 (PL Xin), where their relations to moraines may be readily seen.
