the highway; an earlier position of Maumee wave-work is seen in a 
typically developed ridge about 20 rods farther south. Proceeding 
eastward, the top of the wave-cut Whittlesey slope bears Maumee 
sand and gravel continuously to the Ashtabula River. On the east 
side of the river no evidence of this shoreline is seen until within a 
few rods of the margin of the sheet, where we find a stretch of shore 
gravel about an eighth of a mile long. 
These segments of the Maumee shoreline range about the 760- 
foot contour. In places where the sand has been drifted into knolls 
higher elevations are reached, even 800 feet, as southwest of Ashta- 
bula; the location of such sand is indicated on the map (Fig. 1) by 
small triangles. Along modern as well as ancient shorelines sand is

due to knolls of wind-drifted sand belonging to the Maumee beach. 
frequently found in knolls or dunes reaching 20 feet, and occasionally 
100 or more feet, higher than the general level of that particular 
water stage. For this reason, the beaches above described may 
appear in places to indicate a higher Maumee shoreline; the possi- 
bility of erroneous interpretation here, because of drifted sand, has 
been pointed out by Leverett.^ 
Lake Whittlesey 
On the Ashtabula sheet the Whittlesey shoreline, about 740 feet 
in altitude, is a conspicuous topographic feature. It has been sec- 
tioned by Cowles Creek a short distance south of Geneva, and by the 
Ashtabula River in the southern portion of the village of Ashtabula. 
Its water slope ranges from 10 to 40 feet in height; the back slope of
