Garden Bluff hill, and the descent from the beach to the bed 
of Puffy creek below is 75 or SO feet and quite steep. At Van's 
Harbor there are some light fragmentary beaches on the south 
slope of the hill north of the village at about 30 feet above 
the lake. On the top of the hill, at about 90 feet, there are also 
faint evidences of wave action. About a half-mile north a 
small knob, partly on the land of Mr. Deloria, rises 30 to 40 
feet higher, but it was not closely examined. The road from 
Garden northward crosses a great rolling sand plain about 
ten miles wide. This plain begins near Jack's bluff, which is 
about six miles north of Garden and rises steeply from the 
shallow water of the north end of Big Hay de Noc. The hill 
is composed of fine gravel which gives a strong impression of 
wave wash. Its summit is nearly 150 feet above the lake, but 
no distinct shore lines were found upon it. 
The plain appeared to be composed almost entirely of wind 
blown sand and is heaped tip in great rolling ridges of dunes, 
some of which rise to an altitude of more than 200 feet above 
the lake. In some of the hollows, especially along the bor- 
ders of two small ponds, gravel was found, suggesting that 
the sand may be largely underlaid by that material. On ap- 
proaching the railroad heavy ridges of gravel were crossed, 
some of them resembling beaches, but none observed were dis- 
tinctly of that form. North of the gravel ridges, clay drift 
with limestone slabs again appeared. 
Cook's Mill. At this place several rough and irregular 
hills of drift rise to a considerable bight out of the sand plain. 
On the south side about half a mile north of the station we 
found low beach ridges of tine gravel at an elevation of about 
170 feet above the lake. In two places where the road rise< 
to a level higher than this beach the composition of the hill 
was found to be waxy boulder clay. The area of sand and 
gravel forming the plain is at this place continuous up to the 
level of the highest beach. The hill rises about 60 feet above 
the highest beach, and from the top we could see that the hill 
extends northeastward at least two or three miles. This hill 
formed another link in the island chain which represented the 
Garden peninsula at the epoch of submergence. No doubt 
there are more hills of this sort toward the northeast belong-
