The sods of the fields at its border overhang and vegetation 
is almost entirely absent from its front. About two miles 
south of Sheboygan the plateau of drift descends gradually to 
the level of lake Michigan and merges into a swampy tract. 
The lakeward front of this swamp is bordered by a bench 
ridge of gravel, covered by more or less wind-blown sand. 
This ridge is narrow and the gravel is not above the present 
reach of the waves. No evidence of a shore line was seen on 
the slope above the swamp. Northward from Sheboygan the 
fresh cut bluff extends out of sight. The low tiat south of the 
Sheboygan river, upon which part of the town is built, sug- 
gests a corresponding shore line at that level, but no other 
evidence of it was found. At the east end of St. ('lair street 
there is a terrace, which has been largel}' modified by recent 
improvements. It probably corresponds to a shore line at some 
time in the early postglacial history of the lake, but no other 
evidence of such a line was seen. 
At Manitowoc the shore presents the same appearance of 
freshly cut bluffs of glacial clay. For 100 to 200 yards oil' 
shore at both these places the lake is shallow, suggesting the 
existence of submerged terraces. North of Manitowoc the 
bluff becomes much lower. At one place where a small stream 
enters near the town the low bluff is composed of bright red 
clay, upon which the waves of the present lake have thrown 
up a considerable quantity of white limestone pebbles. At 
Two Rivers, about six miles northeast, the bluff passes inland, 
and the shore becomes a wide, sandy plain close to the level 
of the lake. This plain projects into the lake as a bluntpoint 
and is no doubt in part a delta of the two rivers. 
Kewaunee. Fresh bluffs of clay extend along the lake shore 
here the same as at the places already described. But the 
Kewaunee river has extensive tlats, which are only slightly 
above the level of the lake. At the town they are about three- 
quarters of a mile wide, and along the north side against the 
foot of the high bluff is a distinct cut terrace about fifteen 
feet above the level of the lake. The face of this bluff is ap- 
parently in a stable condition and east of the road is mostly 
covered over with a clean turf. At the lake front the bluff 
projects southward in a sharp point, fresh outside and old in- 
side. About a mile and a half west of the town, where the
