Very extensive deposits of water-worn drift occur in some of 
the larger stream valleys. Inthe upper Genesee valley immense 
deposits of stratified drift are mingled with the till, and much of 
it inextricably confused with the local lake sediments and subse- 
quent stream detritus. South of the divide between the south- 
flowing and north-flowing waters the valleys are choked with the 
glacial wreckage converted into stream drift. Upon the north 
or Ontario side of the divide the glacial drift of all kinds has 
been retained and used, by the combined action of streams and 
glacial lakes, to fill depressions and thus give the smooth surface 
and arable soil of all the region between Syracuse and Buffalo. 
Lesser kame areas—TYo enumerate the smaller deposits of 
gravel or sand left in billowy or mound-and-basin topography 
would be tedious, even if it were possible. Those immediately 
about Rochester have already been described by the writer. 
Other limited deposits occur in many places. Sometimes they 
are barely distinguished from the general drift sheet. Some- 
times they are indicated by a few low mounds projecting 
from the sheet of lake or stream drift which has almost buried 
them. The limitation of such lesser areas is indefinite, as they 
blend into the prevailing sand or silt plains. At low levels, 
without close examination, dune sands may be mistaken for 
kame deposits. 
One area, which merits fuller description than can now be 
given, is found north and south of Palmyra, Wayne county. 
This deposit is not large in amount of material or extensive in 
area but is interesting on account of the development of typical 
eskers, lit) consists Yohyan yinregular,, broken) seres Jor kame 
mounds and esker ridges lying in the north and south valleys 
between heavy drumloids, and extending northward from near 
Manchester, Ontario county, past Palmyra to beyond Marion, a 
distance of about twelve miles. North of Palmyra and north of 
Marion are well-developed, typical eskers. At the southern end ot 
the system, near Manchester, the sand deposit is more extensive.
