Abandoned Shorelines of Vermilion Quadrangle 237 



eastern margin of the sheet the Maumee beach turns directly 

 south, bordering a bay in the Beaver Creek depression of the Ober- 

 lin sheet.* The extensive quarrying operations at South Amherst 

 have made definite mapping of the beach in this locahty impossible. 

 Through part of the distance the shore gravels have probably 

 been removed, and elsewhere the dump of quarry rubbish has 

 covered up the beach; locally the shore line was registered by a cliff 

 in the sandstone which has been quarried. I have mapped shore 

 gravels and one lagoon near these quarries at an altitude, accoiding 

 to the topographic sheet, at least 10 feet higher than the Maumee 

 level elsewhere. It is very likely that a slight error has been made 

 here in sketching the topography. In texture, the entire length of 

 this beach east of the Vermilion River is prevailingly fine. 



LOWEE MAUMEE 



As already suggested, it is impossible at some points to distin- 

 guish the two Maumee levels. This condition is due largely to 

 dune deposits, though post-glacial weathering may be a contribut- 

 ing factor. 



Extending eastward from the rock hills near Berlin Heights the 

 shore line of the lower Maumee level forms a distinct ridge to 

 the vicinity of Ogontz; within this distance are two short spits 

 which developed from cusps. Just east of Ogontz the two shore 

 lines blend because of a cusp built out from the higher level, to 

 which the lower beach was joined, the difference in level having 

 been rendered less distinct by wind deposits. From this point, 

 the lower Maumee beach bears northward ; through part of the 

 distance it is a little over a quarter of a mile wide, and consists 

 mostly of very coarse material. The 750-foot contour outlines the 

 beach until it turns again eastward. At the angle of the turn 

 there is a spit, separated from the shore proper by a lagoon. 

 Post-glacial drainage has cut through the beach just east. Con- 

 tinuing as a single ridge (fig. 2B), it is followed by a highway to the 

 edge of Chappel Creek. In this area a small bay marked the lower 

 Maumee level as is shown by the turn in the beach as well as by a 

 spit, about one-quarter mile long, built eastward from this angle.
