to the north and eastj we note a topographic environment that 
directed into this area of kames a large amount of drainage both 
along the general front of the ice and from the higher ridges towards 
Virgil in the Cortland quadrangle. A more or less stationary 
ice mass bearing a considerable load offers an added explana- 
tion for the peculiar localization of stratified drift and of outwash ; 
deposits found in the vicinity of Freeville. While this discussion i 
has emphasized a relationship that existed for some time as shown 
by the valley loops already described, I am not overlooking 
the fact that this somewhat stationary position of the ice probably i 
was slowly reached and as slowly receded from; during this 
period of gradual change a great amount of gravel and other 
washed material was accumulating. 
While in the main I have considered the kame areas in the 
Freeville-McLean region as quite identical in development, 
there are, nevertheless, some features that indicate partial inde- 
pendence of origin. By consulting the topographic map we note, 
a short distance east of Red Mill, a slight creek that follows the 
sags across the irregular drift reaching ultimately out onto the 
flood plain. The limited catchment basin which this stream has, 
when considered from the standpoint of the well developed crease 
it occupies, proves the former erosive work of an active stream. 
This fact leads me to conclude that the kame area south of McLean 
is in part of later chronology than the Freeville kame area. The 
creek occupies a valley which it never could have cut with any 
such amount of water as might flow under normal conditions 
from the basins which it drains. Its more mature course has an 
axis which leads it westward of the Freeville kame district. In 
other words, the portion of the Freeville kame area that reaches 
nearest Red Mill was in existence when ice-front drainage cut 
the channel now occupied by this slight creek, and accordingly 
it is concluded that the conditions for drift-accumulation were 
present in the vicinity of McLean long after the ice had entirely 
withdrawn from the immediate region of Freeville. The portion 
of the McLean kame area which probably is contemporaneous 
with the first formed part at least of the Freeville kame area lies 
near the eastern wall of the Fall Creek valley in the vicinity of, and 
immediately south and east of, Mud Pond. 
The connection of the Malloryville esker with the washed drift 
north of this village is discussed in the chapter on Eskers. It may
