range is loo feet and possibly somewhat greater; (6) southwest of 

 West Beekmantown one and one-half to two miles the range is 80 

 feet (600-680 feet A. T.) ; (7) three to three and a half miles north of 

 the latter place, and about the same distance southwest of West 

 Chazy, the range is 95 feet (605-700 feet A. T.). The lowest terrace 

 of this series when projected southward connects with the bottom of 

 the Fort Edward Valley. 



Lower series of wave- wrought terraces : A gap intervenes between 

 the lower terrace of the upper series and the upper terrace of the lower 

 series, in which the signs of wave- action are either very faint or alto- 

 gether lacking. Because the lower series of terraces is often fainter, 

 there is some uncertainty as to the amount of this gap. At Street 

 Road it seems to be about 120 feet; at Crown Point 100-120, and 

 possibly 140 feet. At Port Kent this gap is 124 feet (380-504 feet 

 A. T.). At the Saranac River it is not known exactly. It is as much 

 as 120 and no more than 165 feet. West of West Chazy it is 155 feet. 

 The upper part of this lower series of terraces has been examined 

 at a few points only; namely, west of West Chazy, where distinct 

 terraces and beach ridges range from 450 down to 400 or 380 feet 

 A. T. Other lower levels not systematically studied are to be seen 

 east of West Chazy. At Port Kent an extensive series of terraces and 

 beach ridges and bars was observed to extend from an elevation of 

 380 feet well down toward present Lake Champlain level. There 

 were at least thirteen levels represented. The terraces of the lower 

 series are best brought out along the streams. They have been 

 observed on the south side of the Saranac, where sixteen levels were 

 observed between an elevation of 300 feet and the level of Lake Cham- 

 plain. They also occur on the Salmon River. At some of these 

 levels, low-level deltas were built. Between Port Henry and West- 

 port the low-level terraces may be represented at several places. At 

 Crown Point a delta level appears to be present at 180-200 feet A. T., 

 and indistinct terraces below this level have been seen south of Crown 

 Point. 



At Street Road distinct terraces occur at 160-180 feet, and indistinct 

 terraces are perhaps represented up to 220 feet A. T. The upper 

 terrace of this series projected southward falls below the Fort Edward 

 valley.
