the north portion of the narrow valley that was the long divide 

 between the Hudson and Champlain ; no^w cut by Wood creek. 

 The only large stream is the Mettewee river. Its delta in the sea- 

 level waters is apparently the filling at and above Granville, on the 

 Vermont line. 



Whitehall quadrangle. Sufficient examination has not been given 

 to this area to speak with confidence of the features. Good shore 

 phenomena must not be expected in such narrow valleys. The 

 small deltas of the torrential streams will be the best criteria for 

 the water levels. The marine altitudes are about 490 at the south 

 edge of the sheet and about 530 feet at Stony Point, the north 

 edge. The waters occupied the crooked valley of East bay and 

 Poultney river, and passed far east to the Green mountains in 

 Vermont (92). 



The evidences of standing water are very clear from the trains 

 of the Delaware and Hudson Railroad. 



Champlain Valley 



Ticonderoga quadrangle. On this area the estuarine waters were* 

 very irregular in shape, and the shore features about the hills on 

 the eastern side of the lake have not been examined. The eastern 

 shore of the estuary lies far eastward in Vermont, beyond Bran- 

 don and Middlebury, against the west flank of the Green moun- 

 tains. The Vermont features are described in the Vermont report, 

 paper 92. 



On the west side of Champlain the shore features are well known, 

 having been described by several authors, though not always with 

 the correct interpretation (75-77, 82, 94). . 



The sand and clay plains representing inferior levels of the Cham- 

 plain waters are conspicuous. They appear along the railroad 

 from Baldwin to Ticonderoga, at 340 to 360 feet; north of Ticon- 

 deroga over a large area between the lake and the highland, at 

 260 to 280 feet; and especially in the embayment west and south- 

 west of Crown Point, ranging from 200 to 480 feet. The theoretic 

 marine plane lies on the west edge of the sheet at about 525 to 

 565 feet, or along the meridian of the lake at 530 on the south to 

 572 on the north. 



This summit level of the sea-level waters is registered in the 

 Crown Point district by gravel bars. The best series occurs 3 

 miles northwest of Ticonderoga and a mile north of Street road, 

 on the east face of a kame-moraine, locally known as Sawyer hill. 

 This locality was cited by Baldwin in 1894 (75, page 176) ;
