forest is of a much mixed wet hardwood type, sugar maple, 

 linden, yellow birch, elm, and hemlock, being the dominant 

 species. The forest in most places reaches the edge of the 

 lake, though a few sandy beaches occur. However, the level 

 of the water in the lake has been raised a few feet by a dam 

 across the outlet, and beaches were probably more abundant 

 before this occurred. The lake is so large, about 13 miles long 

 by I to 2 miles broad, that wave action is cjuite pronounced. 



One beaver meadow was studied, this meadow including 

 areas of grasses and of sedges, traversed by ditches, small 

 mud-flats covered with low rushes, and alder thickets. 



Just north of Lake Gogebic Station there are some high hills 

 having bluffs on the southern exposures. These hills were 

 visited, but they had been extensively logged and burned over 

 and no attempt was made to trap for mammals on them. 



Some large burned areas have grown up to sapling forests 

 of aspens. Near the towns of Lake Gogebic and Merriweather 

 nearly all the forests have been cleared away, but farther south 

 on the sides of the lake the woods are still in their natural 

 condition.
