892 The American Geologist. June, 1897 
LAKE ADIRONDACK. 
By B. F. Tatlok, Fort Wayne, Ind. 
Early in October, 1893, I joined professor J. W. Spencer for 
a reconnoissance of the slopes of the northeastern portion of 
the Adirondack mountains. The trip was made on Prof. 
Spencer's invitation, and his lead was followed. Our efforts 
were directed toward a search for evidences of Pleistocene 
submergence, and more especially to an attempt to trace the 
Iroquois beach at high levels. 
The Iroquois beach had been traced by Mr. G. K. Gilbert 
along the south side of lake Ontario and northward along the 
east side to cape Rutland, about four miles nortl)east of 
Watertown, several j^ears before.* To this point the beach is 
a prominent feature, easily traced, but the character of the 
country changes here to one of rocky knobs, largely bare and 
with sandy wastes between. Gilbert and Spencer both made 
repeated eff'orts separately, and once jointly, to carry the 
tracing farther, but without much success. Mr. Upham also 
entered the field with Mr. Gilbert. As a result of his several 
excursions Prof. Spencer believed that he had traced the Iro- 
quois beach in somewhat modified form past Carthage, Natu- 
ral Bridge, Harrisville, P^ast Pitcairn, Fine, Clarkesboro, and 
South Colton.j- Just before we met he had taken up the line 
again at South Colton and carried it farther northeast past 
Parishville and Dickinson Center and on the south to a point 
on Salmon river near Owl's Head station about ten miles south 
of Malone. 
It is not the object of this paper to go into details of the 
observations made except in two or three instances. A few gen- 
eral statements of results will suffice. Terraces were seen in 
the distance near Siandish, on Upper Chateaugay lake, but

The writer also made an attempt to trace this beach northeastward 
from Watertown, early in November, 1893, but with only limited success. 
It seemed to be traceable in one form or another along the line indicated 
by P)-of. Spencer to the vicinity of East Pitcairn. But it passes thence 
to the north by South Edwards and Edwards. Littoral features doubt- 
fully referred to this beach were followed still farther north from Ed- 
wards to Russell and thence northeast to Colton.
