railroad ascends from the swamp to the higher ground, it 
crosses a gravel ridge with a lagoon hollow behind it. We did 
not have an opportunity to examine this ridge with care, but 
it is probably a true beach, for it faces toward the open lake 
and its crest is about twenty feet above that level. These two 
forms were the first positive evidences of postglacial submer- 
gence observed on this shore. Along the open lake shore near 
the town, however, modern wave action has entirely removed 
this beach. The fiats of the Kewaunee river extend inland 
about five miles. Apparently the valley was excavated by the 
river when the water of the lake stood at a lower level than 
now and it was filled up with tine sediments at a later period, 
when the lake stood at or near the level of the shore line des- 
cribed. 
Green Bay. This place is about twenty-six miles west and 
six miles north of Kewaunee, and the shore line was found at 
about the same level. Near Bay Settlement, about four miles 
northeast of Green Bay, we found the beach developed as a cut 
terrace against the base of the high and heavily drifted coast. 
Within the eastern limits of the town the beach occurs in the 
form of low sand ridges, which are well developed at several 
localities. A very distinct one is not far below the mill at 
the foot of the hill northeast of town. It is about fifty feet 
wide and four or five feet above the surrounding plain. On 
the west side of Fox river the country back of Fort Howard 
slopes upward to the west very gradually. On this slope we 
did not find the highest shore line clearly developed, only a 
few faint sand ridges remaining as evidence of submergence. 
We ascended the hill east of Green Bay about 150 feet, but 
saw no evidence of submergence at higher levels. 
Sturgeon Bay. At this place we found a line series oi' de- 
serted beaches, the crest of the highest being about thirty-live 
feet above the lake. The highest beach is a finely formed 
shingle ridge, composed mostly of limestone pebbles. This 
beach is not very heavily developed and is rather narrow, but 
it is remarkably distinct and extends for a distance of five 
and a half miles toward the northwest, to a precipitous lime- 
stone cliff half a mile beyond the house of Mr. Roberts. The 
lake shore drive follows the top of the ridge for a considera- 
ble part of the distance. The lagoon hollow behind is very
