Company's pit. Presumably, water that flowed through breaks in the 
ridge on the east side of the Buzzards Bay moraine or directly from 
the face of the Buzzards Bay glacial lobe superimposed fans on top 
of the main plain at these two localities. 
Associated Older Gravels 
At two other places constructional gravel deposits rise above 
the general surface of the pitted plain. The most conspicuous one 
is Falmouth Heights on the shore of Vineyard Sound. The present 
shape of the deposit is elliptical, and its top is 35 feet above the 
adjacent plain. On the seaward side a 40-foot wave-cut cliff cone 
sists entirely of crossbedded sand and gravel. In the upper layers 
of the gravel are many ventifacts. This gravel must have been de- 
posited as outwash from the ice prior to the building of the pitted 
plain, for its altitude implies ice or other gravel immediately sur- 
rounding the present site to enable streams to deposit at sucha high 
level. This deposition occurred before any other event registered 
by the surface deposits on this end of Cape Cod. Presumably it oc- 
curred while the ice front was retreating from Martha's Vineyard to- 
ward the line of the Buzzards Bay and Sandwich moraines. Originally 
the deposit may have been far more extensive, If so,most of it must 
have been removed, in part by streams from the ice that was retreat- 
ing north and west of it long before the low outwash fan was built 
around it and in part by ocean waves which are now active at present 
sealevel. 
It is more than likely that this body of gravel never extended 
very much farther toward the north than it does today, and that it 
represents the apex of an outwash fan built southward from an ice 
front that was temporarily standing close by the Heights. Rather 
rapid recession of the ice then removed the support from the north 
Side of the fan, and subsequent outwash deposits were never built to 
so great an altitude. 
The other outwash deposit above the pitted plain is a discon- 
tinuous, broad, low ridge trending southeast from the edge of the 
Sandwich moraine north of the Cape Cod Airport into the plein as far 
as the Barnstable-Falmouth Road. At its northwest end, this ridge 
blends into the moraine front;at its southeast end it is half a mile 
south of the moraine. Its undulating crest rises 10 to 25 feet above 
the adjacent plain, and it consists of well-bedded and crossbedded 
sandy grevel without boulders. The gentle south slope and slightly 
steeper north side of the ridge suggest that it, too, was deposited 
by glacially-fed streams when the ice edge stood close to or along 
its northern margin. 
Till Clumps in Gravel 
Till is not ordinarily found in glacial outwash. Till comes di- 
rectly from ice; gravel is washed and sorted by the meltwater. Ir- 
regular clumps of till were found, however, in excavations at six 
localities in the Mashpee pitted plain in the midst of gravel far
