broken by points and islands. An extremely good example of this 
type of lake is Milpagos, whose many points and islands are moraines. 
Indeed it would be difficult to find in the province two finer examples 
of the two extreme forms of Glacial lakes than Long and Milpagos. 
Of course there are all gradations between these types. Of morainic 
origin are the many islands in Island or Milnagek Lake, which have 
their long axes parallel and nearly northwest and southeast. The 
great peninsula dividing Trows- 
ers Lake into two “ legs ” is 
largely, if not entirely, a huge 
moraine. The valley in which 
this shallow lake lies is evidently 
largely drift-filled. 
So much for the origin of the 
present lakes. The question now 
arises as to the origin of the 
valleys in which they lie. Of 
these there are several, partially 
parallel, but with a tendency 
to a radiation southward and 
convergence northward, a fact 
brought out with the greatest 
clearness when we shade them 
along their approximate axes, as 
has been done in the accompany- 
ing map. Very distinct is the 
valley occupied by the chain of 
lakes from Furbish Pond to 
Trowsers Lake, and this is the 
longest and perhaps the main 
valley, into which the others 
fall. Gulquac occupies a parallel valley, and perhaps emptied 
by some of the Ogilvie Lakes into Trowsers. Possibly Island Lake 
belongs really to a smaller valley of the eastern leg of Trowsers, 
and its fall into Long Lake may be post-Glacial. Particularly distinct 
is also the Long Lake valley, and the depth of Long Lake shows how 
deep the valleys may have been.* Another is the Portage-Hind- 
* Possibly this depth is due in part to the gouging action of glaciers, but damming of a 
deep valley seems more probable.
