the embayment. The middle third of this has since been removed 

 by stream erosion. 



5 Prior to open-water conditions, a marginal lake may have been 

 impounded in the western end of the embayment. This lake was 

 drained by the marginal stream that flowed southward between 

 Breed mountain and Buck mountain. It formed the Sawyer hill 

 marginal moraine where it issued from the Vineyard pass. 



6 The evidence afforded in this locality supports the hypothesis 

 that all the shore lines were formed in an open body of water at a 

 time when the ice had retreated to the far north end of the valley. 



7 The shore lines about Crown Point correlate with the several 

 stands postulated by Woodworth. They tend to support his 

 hypothesis that these stands were conditioned by the wearing down 

 of certain outlets to the south.
