WISCONSIN TILL 547 



In a road-cut li/^ miles east of Gorham, Maine, about 5 feet of bouldery 

 till were seen resting on 2 feet of stratified 5and. 



Along the Wiscasset, Waterville and Farmington railroad good 

 exposures of till over gravel were seen. 



In Whitneyville, near Machias, Maine, a section shows 2 feet of stony 

 till overlying sand. A sand plain one-half mile or more in extent at this 

 place is covered with large boulders, giving the appearance of Wisconsin 

 till. 



In Columbia Falls, Maine, 1 to 5 feet of till containing boulders up to 

 3 feet in diameter rests on sand. 



The following section was seen at Brewer, Maine, in a gravel pit a 

 short distance above the bridge across the river :

At East Orland, Maine, a well starting on a slope thickly strewn with 

 large boulders was drilled through 87% feet of sand, striking clay and 

 obtaining a large amount of water. 



A number of wells dug and drilled elsewhere in Maine report quick- 

 sand beneath the till which forms the surface. 



In an exposure in Lynn, one-half mile north of East Saugus, Massa- 

 chusetts, there is a section of partially stratified gravel upturned at an 

 angle of 30. degrees and overlain by 2 to 6 feet of till. The gravels, 

 although of a type that would ordinarily be called morainal, appear to 

 have been originally horizontal, like those commonly found in sand 

 plains and to have been contorted by overriding ice which deposited the 

 till over them (see figure 7). 



In a gravel pit one-half mile west of Danversport, Massachusetts, 2 to 

 8 feet of gravelly till were seen overlying 10 to 20 feet of horizontally 

 stratified sand. 



On page 515 a section at South Lawrence, Massachusetts, was de- 

 scribed, in which 1 to 6 feet of till overlie 2 to 5 feet of stratified sand, 

 which in turn overlies older till (figure 2). 



4. Slight surface oxidation. — While the dnimlin sections and other 

 exposures of thick till of the Montauk type are normally yellowed by the 

 effects of oxidation to a depth of 10 to 20 feet from the surface, the 

 upper till, notwithstanding its being looser and more pervious, is never
