Sipe oF THE CoNnNECTICUT RIVER. 
This view shows the upper ten feet of the section of which Plate 4, fig. 1 is near the bottom. The 
annual deposit at the bottom is about six inches thick, while near the top the annual deposit is not over 
one inch thick. The bands grow thinner very uniformly from bottom to top with no tendency to thick- 
ening. From a close study of this deposit it is inferred that the cause of this progressive thinning is 
due to retreat of the glacier and the consequent diminution in the supply of material as the glacier 
withdrew. About fifty annual deposits can be counted from the bottom to the top of the bank, which 
is three feet above the top of the view. This includes about twelve feet. From the comparatively 
thick annual deposits at the top (about 2 inch) it is believed that much of the original deposit has been 
eroded. The entire section of sands and banded clays is about fifty feet thick above the till at the 
bottom. See Plate 4, fig. 1 for a description of the lower part of this section. 
Figure 2.— Banprep Siate at Squantum aout 150 Farr apove tar Truurn. 
Shows regular banding averaging about one inch for the fine and coarse layers. Just below the 
hammer is a zone of crumpling nine inches thick. Near the lower left corner some small pebbles may 
be seen mashed into the folded layers. Another zone of crumpling about three inches thick may be 
seen at the top. A small pebble also shows in this zone. The layers do not show progressive thinning 
here, simply differences in thickness, probably due to normal variations in seasonal temperatures or 
precipitation. :
