with liaised Beaches of Lake Erie. 287 



opposite the place where streams tributary to the lake had 

 their debouchure, it is much larger, standing 12-15 feet above 

 the plains either side of it and having a breadth of 20-40 rods 

 or even more. 



The beach apparently terminates at a cemetery near the 

 south bank of Blanchard river in the western part of Findlay. 

 It is here in the midst of a plain that rises gradually toward 

 the north, the east and the south, so that the lake at its eastern 

 terminus was a mere point and its waters quite shallow. The 

 beach is about as well developed at its eastern terminus as it is, 

 on the average, west from there, so there is no difficulty in 

 tracing it. Along the north side of Blanchard river, west 

 from Findlay, no well defined beach of corresponding age with 

 the Yan Wert ridge appears. It is evident that the plain 

 between the river and the Blanchard moraine was submerged, 

 for it is coated in places with sand and gravel, and much of it 

 is as low as that between the river and beach on the south. 

 Sand also sets in on the outer (south) slope of the Blanchard 

 moraine, a few miles west from Findlay, and reaches altitudes 

 as great as on the beach south of the river, but I could trace 

 no shore lines. » 



The strength of the beach at its eastern terminus raises the 

 suspicion that the ice may have been more remote when the 

 principal work was done on the beach and afterwards re- 

 advanced to the position indicated by the moraine, for the 

 water between the beach and the moraine constituted a narrow 

 pointed bay and as a rule the beach following the side of such 

 a bay is not as strong as the beach facing a broad sheet of 

 water. However no conclusive evidence of such a re-advance 

 of the ice-sheet- was discovered. The phenomena along the 

 moraine as shown below seem to indicate that the ice-sheet 

 overhung it while the lake was still occupying the Yan Wert 

 beach and thus prevented the waves of the glacial lake from 

 making their impress on the moraine. 



(6) The Blanchard Moraine. — The Blanchard is the latest 

 moraine of the series in Ohio that can be traced around the 

 western end of Lake Erie. Its course may be seen on the 

 accompanying map (fig. 1). Westward from Findlay the 

 moraine is on the wholes less conspicuous feature than east- 

 ward from that city, but may be easily traced in a curving 

 course northwestward to the Maumee just below Defiance, and 

 thence north into Michigan. The portion of it west from 

 Findlay was discovered and mapped by Mr.. Gilbert more than 

 twenty years ago.* It is therefore one of the earliest recog- 

 nized moraines on this continent.
