fossils, fragments of the delicate ske letors c2 sponges and diatoms 
that were common in Pleistecere and Recent tine and lived in marine 
or crackish watere- The preserce of such =aterials in glacial lake 
sediments that now stard over a hundred feet above the sea is not 
puzzling when we consider that these silts an = ee sands were 
originally ore d during construétion ofthe moraine of which they 
sral part and that the ice from which these sed-

Senayich Moraine 
Location and Character 
A secord belt of ruxmocky and relatively high terrain, known to 
the natives as the “backbore” of Cape Cod, lies close to the north 
side of the upper arm of Cape Cod apsroximately parallel to the shore 
of Cape Cod Bay. As stated on page 14, Woodworth considered this a 
part -of the Falmouth m ase), contemporaneous with the other portion 
here designated as the Euzzards Bay mordine,but it is found that the 
till of the two moraizic teits ts distinctly different in some re- 
spects and it is belie trat this east-trending moraine overlaps
