J. D. Dana—'Kames” of the Connecticut River Valley. 465 
Norwich, Vermont.—The continuation of the Hanover “ kame” 
to the summit of the high terrace, crossing the “ kame” where 
its height is 565 feet (Upham), half a mile south of the highest 
point, 600 feet. Along the road are sections ag the deposits, 
showing the inner nature of the Norwich “kam 
road commences the mre some paublé, stones lie scattoed over 
the surface, such as been found common along the road at 
the base of the “ aca for the half mile or more ye the south. 
Above this, for the next hundred feet, there is sand, finely 
straticulate, with occasional fine gravel. Nearing the top, 
the beds become coarse gravelly, and then there are large 
cobble stones; and this upper coarse-gravel portion rises above 
the crest of the so-called “kame.” In the higher part, to the 
north, some stones, as stated by Upham, are 4 to 5 feet in di- 
ameter and angular. 
Nothing was observed on the ascent from the river, or on 
the west side, to suggest a suspicion that this cobble-stone de- 
posit was the top of a narrow range of coarse gravel beds bu- 
ried beneath the terrace- -formation ; on the contrary, the evi- 
dence from the sections along the ascent, and sete: 2 the suc- 
cession of beds toward the top from san s to gravel beds, 
and then to the coarse cobble-stone give atrongl y confirmed 
the natural inference that all was one consecutive series, with 
the cobble-stone deposit the uppermost and a. the latest. 
West of the cobble-stone ridge, or the ‘‘ kame,” the terrace has 
great extent. The surface falls off snamaesateee 40 feet, expos- 
ing the materials that lie beneath, and these are sand and fine 
gravel as on the east si 
The Pompanoosuc river was probably oe chief source of ie 
coarse material of the summit. To the southwest, about t 
village of Norwich, she terrace is quite tian over much of its 
surface from the contributions to the terrace of Blood Brook. 
In Thetford the “kame” becomes very low before the village 
is reached. 
The other reputed “ kames” of the Connecticut River shore 
I have not particularly examined, Butas the line from - 
sor to Thetford is “ the kame of the Connecticut valley,” essen 
tially “a continuous gravel ridge or kame, extending 24 miles,’ 
and is made, ir Mr. Upham’s work, the text for the description 
of “ kames” in general, details from the other minor “kam 
in the valley are not necessary for a right concha see
