only one of a score of similar hanging valleys. Buttermilk

creek (Fig. 9), south of Ithaca, likewise approaches the edge 
of the Cayuga valley wall in a broad, mature valley, then, at 
about the 900 foot contour, tumbles over the valley wall in a 
post-Glacial gorge. Here, too, there is a drift-filled gorge of 
earlier date. Practically continuous rock, eliminating all but 
gorge valleys, can be traced at the 800-900 foot level. This 
valley is therefore hanging at least 945 feet above the rock 
floor of Cayuga valley at Ithaca, two and a half miles distant. 
Lick brook, (Fig. 10), a short distance farther south, shows 
the same condition.

Newfield creek, on the west side of Cayuga valley, presents 
the same phenomenon, its hanging valley floor at Newfield 
being over 950 feet above the rock bottom of the main valley at 
Ithaca. Coy Glen, just to the north, is in a hanging valley 
over 950 feet above the main Cayuga valley ; and the valleys of

Taughannock ( Fig. ii ) and Trumansburg creeks hang at least 
845 feet above the rock bottom at Ithaca, and also above the 
deepest point (435 feet) in Cayuga lake, seven or eight miles 
distant.
