Directly north from this locahty my map shows scattered 

 Maumee deposits. All of these rest immediately upon the Berea 

 sandstone which in this region has scarcely any covering. The 

 two areas west of the north-south highway consist of quite coarse 

 rubble. The crescent-shaped area east of the highway is made up 

 of slightly finer material ; if I had been able to trace beach deposits 

 between this and the arm of sand and gravel extending northward 

 from near the middle of Murray Ridge, I would not hesicate to 

 make it the shoreline of the lower Maumee. The ridge that ex- 

 tends north, crossing the electric line, and bearing thence to the 

 west, parallels a lagoon for seven-tenths of a mile. This ridge 

 increases in strength of development northward ; its west or in- 

 land slope is short and steep. A recently constructed railroad, 

 about twenty rods south of the electric line, reveals a section ; at 

 this point it consists of coarse, well-rounded stones; finer' gravel is 

 found as the ridge turns westward. The two short spits are com- 

 posed of fine sand; one of these so encloses a lagoon (fig. 2) that 

 it is difficult to conceive of its originating in any odier way than in 

 very shallow water. It is quite evident that this region of Berea 

 sandstone, north of the Lake Shore railway, formed a shallow place, 

 like a submerged cape, in lake Maumee, and that these scattered 

 areas of beach deposits were constructed during. its .declining stage. 



Islands. — About a; mile east of North Amherst, the area 

 marked "Quarry" on the topographic map (fig. 3) formed a small 

 island in the Maumee stage. Its slopes were steepened by wave 

 work; to its eastern end is appended a spit. The part of the island's 

 surface that was above water now bears wind-shifted sands. 



THE WHITTLESEY SHORELINE 



The Black river depression was occupied by a broad bay dur- 

 ing the Whittlesey stage. The outcropping sandstone on the west 

 - formed a peninsula, making a break in the regular east-west direc- 

 tion of the shore. The general altitude of Lake Whittlesey is about 

 730 feet ; a beach structure characterizes its shoreline on the Ober- 

 lin sheet. 



]\\-'st of Black river. — Near the west margin of the sheet 

 (plate VII) Beaver creek has cut the beach for a short distance. 

 Immediately on either side of this creek the shore ridge consis:s 

 chiefly of fine sand. To the east, as the shoreline bears northward,
