THE KALAMAZOO AND OTHER GLACIAL OUTLETS 481 
At Dimondale the Grand River enters the valley from the 
southeast and follows it to Lansing, a distance of nine miles, 
where, after receiving Cedar River, it passes through the Charlotte 
moraine northwestward. The marshy tract between Dimondale 
and Charlotte is drained westward through the Thornapple, 
while below Charlotte the drainage is effected by Battle Creek. 
At Otsego the Kalamazoo leaves the old channel and passes out 
westward through a narrow gorge inthe Valparaiso moraine. 
The elevations of railroad stations which appear to be situated 
about on the Jevel of the valley floor are as follows: Lansing

the waters of the Imlay outlet during the earlier stage of the 
activity of the latter, as we are inclined to believe, further inves- 
tigations will probably show a connection to exist by way of 
Cohoctah and Lapeer or west of the latter place. However, 
more detailed work will doubtless bring to light other lines of 
drainage and until such work is done no reliable prediction can 
be made. During the time of greatest activity of the Kalamazoo 
outlet when the edge of the Saginaw lobe occupied the position 
of the Charlotte moraine and that of the Michigan lobe was at 
the position of the Valparaiso moraine, the waters from the two 
opposing ice fronts north of Plainwell evidently came down by 
way of the Gun Lake branch. Later when the Saginaw lobe had 
retreated to the north side of the Thornapple River, the princi- 
pal drainage must have been by way of the Thornapple and Gun 
Lake channel. 
The Milford channel——The only part of this channel as yet 
known is the wide valley occupied by the Huron River between 
Milford and Hamburg Junction. It has been suspected that this 
channel connected with the Kalamazoo outlet, but from what has
