KAME AREAS IN WESTERN NEW YORK 131 
mentioned for the first time in print. The Rochester kame- 
moraine need not be redescribed. 
A comparison of the deposits will be made, and an attempt 
to show the relation of the areas to the glacial drainage and the 
larger topography, with a brief discussion of the problems 
involved. (See map, Fig. 1.)

Distribution of water-laid drift.— Glacial sands and gravels are 
very generally distributed over western New York. Limited 
deposits of water-laid drift occur upon even the highest plateaus. 
It is a very common thing to find such deposits upon the sum- 
mits or slopes of the drumloids, and some of the largest excava- 
tions of gravel for railroad ballast and other uses are superficial 
deposits associated with the drumloid or subglacial till. On low 
ground they are very abundant, but at altitudes under 875 feet 
above tide they are frequently leveled or distributed by the 
static waters or buried under lacustrine silts.
