swings southward, in the vicinity of the cemetery; it is not likely that 
any considerable embayment characterized the Whittlesey shore at 
this point, though a slight depression apparently antedated the 
present river channel. 
Immediately east of the river the shoreline consists of two 
ridges, for about one-half mile, a condition which also points to the 
presence of a small bay; in the southern of these two ridges, just west 
of the highway leading south to the river, a gravel pit has been 
opened. Thence eastward for nearly a mile, a single beach ridge 
obtains, built against the moraine (Fig. 4), which, in the early stages 
of the Whittlesey level, must have suffered much through wave- 
erosion. Eastward, near the margin of the sheet, the shoreline shows 
an inner ridge, barrier in origin. 
Lake Arkona 
Two shorelines, approximately 695 and 710 feet in altitude, 
mark the levels of Lake Arkona, which was succeeded by Lake 
Whittlesey. Thus the Arkona beaches were submerged beneath 25 
to 40 feet of water. Modified by wave-work and currents, these 
shorelines are quite indistinct, though in places well-defined beach 
fragments have withstood the attrition processes, and make it 
possible to trace the margin of Arkona waters. 
East of Ashtabula is a mile segment of beach belonging to the 
lower stage of Lake Arkona; it is a few rods south of, and parallel 
with, the Warren beach. For three miles west of Ashtabula, between 
the Warren shoreline and the Electric railway, the map indicates a
