The Abandoned Shore Lines of Green Bay. — Taylor. 321 
was at its highest level. It is surrounded by a distinct cut 
terrace with sea-bluff above. This little island was not more 
than 200 or 300 feet in diameter. From Sawyer the beach 
passed about straight south at the rear of the sand plain to 
the lake shore at Clay Bank. Westward, along the south 
shore of Sturgeon bay. the coast is mainly a precipitous lime- 
stone cliff, where the beach appeared to have no distinct rep- 
resentative. Above the level of the highest beach the surface 
of the country on both sides of the bay presents a character- 
istic rolling glacial topography, upon which no evidence of 
submergence was found. The upper beach in the vicinity of 
Sturgeon Bay is not heavy in its development. On the con- 
trary, it is quite light and delicate, though very clear and dis- 
tinct, and the contrast of topography above and below its 
level is very sharp. This is noticeable at the houses of Mr. 
Snyder and Mr. Roberts. 
The West Coast. The west coast of Green bay slopes up 
from the lake so gradually that its surface has become a great 
cedar swamp. The whole coast from Green Bay to Gladstone 
is bordered by a strip of countiy like this, from two to six or 
eight miles wide. The flats back of Fort Howard are pro- 
longed northward along the shore-. But at several places be- 
tween Green Bay and Menominee the railroad rises to slightly 
higher levels and cuts through banks and mounds of gravel, 
which I take to be remnants of deltas, for they arefoundnear 
the courses of the streams. Such gravels may be seen at Sua- 
oiieo and the Oconto and Peshtigo rivers on the line of the 
North Western railway. We found evidences of submergence 
back of Marinette and Menominee developed clearly enough 
up to a hight of about forty feet. But no definite beach mark- 
ing the highest level was found except at one place near Birch 
('reek station, about six miles north of Menominee. At that 
place there is a distinct beach ridge extending north and 
south along the east base of a rolling drift surface and it^ 
altitude is about fifty feet above the lake. There area great 
many irregular low sand ridges at lower levels near both these 
towns, and there are a few dunes. There is a very large dune, 
or rather a series of them, in the northern part of Menominee 
near the race course. ;md there are more about a mile north- 
west of tin- town. The evidences of submergence are easily
