Lake Adirondack. — Taylor. 393 
their character remained a matter of doubt. Terraces, mostly 
rather faint and poorly formed, were also seen around Chazy 
lake. These suggest the presence formerly of static waters in 
these basins at higher levels than now but nothing indicating 
wave action was seen. 
Passing over to the Saranac valley at High falls, above Mof- 
littville, terraces were found at about 1025 and 1100 feet and 
others at higher levels half a mile northwest of Mofflttville. 
None of these, however, were as distinct and finely formed as 
two terracesthat were found higher up the valley on the north 
side on the farm of Mr. Wilcox, about a mile and a half west 
of Redford. Here, about forty rods back from the road, are 
two flat- topped terraces each with a distinct bluff front, the 
upper about twenty-five feet above the lower. The upper one 
extends a considerable distance back to the northwest to a 
small stream. 
These two terraces are part of an old delta of a creek that 
comes down from a high mountain about three miles to the 
northwest. Standing on the upper terrace we saw a distinct 
bench around the valley on the other side, at about the same 
level. Towards the southwest, and less noticeably towards the 
south and northeast also, this bench was discernible. The al- 
titude of the upper terrace is appi-oximately 1,370 feet (an- 
eroid from Dannemora). Nothing marking a water margin 
was seen at a higher level, but a few terraces and deltas were 
found at lower levels. About a mile east of Dannemora, on 
the south slope of Rand hill, there is a delta of rounded grav- 
el which is cut by the Chateaugay narrow gauge railroad and 
excavated for ballast. Its upper level was not measured, but 
at the pit the top of the bank is about 25 feet high or about 
950 feet above tide, while the top of the delta is probably 
somewhat higher. This delta may correspond with the lower 
terrace at High falls. In the Au Sable valley northeast of 
Black Brook we found a few faint terraces up to correspond- 
ing hights, but nothing so definite. Only a small part of this 
valley, however, was examined. 
After a little over a week together we separated. Prof. 
Spencer going south along lake Charaplain, while I began a 
search for beaches, mostly at lower levels, on the northern 
slope of the mountains. In several favorable places evidence
