In the Whittlesey territory no glacial drainage fell below the 

 Whittlesey level; therefore all detrital plains below Whittlesey 

 level in the Whittlesey area must correlate with land stream 

 drainage. The same must be true of all deposits below the Warren 

 level everywhere. But the materials of the lower land stream 

 deposits were partly, in many cases, brought within the grasp of 

 the land stream by the glacial drainage. 



In most valleys of the region detrital filling occurred at various 

 levels; in local glacial lakes, and at different hights; in Lake Whit- 

 tlesey; in Lake Warren; and in hypo-Warren waters. We shall 

 note only a few of the more important delta plains which have 

 some relationship to the land stream drainage.
