advance, probably contemporaneous with the Wisconsin continental 

 glaciation, then took place, overriding the earlier glacial deposits 

 and locally capping them with later till beds. The extent of this

 material lying far within the outer limit of the last great glaciation. 

 Enough data have not yet been obtained upon which to base a 

 correlation of the older glacial deposits with the earlier stages of 

 continental glaciation.
