Cameron lakes is the highest Algonquin beach. A narrow pas- 
sage If miles east of Kirkfield connected the Balsam Lake em- 
bay men t with the main body of the lake, but there is no good 
evidence that there was any fall at this point. The passage was 
divided into two portions by an island composed of drift. On the 
west side of the island the passage was one-half mile wide with a 
maximum depth of 40 feet. On the east side of the island the 
passage was slightly over one-half mile wide with nearly the same 
maximum depth as on the west side. At the east end of the 
island a strong gravel spit occurs which was evidently built 
directly out into the passage. The passage is very short and 
broadens almost immediately on either side so that it does not 
seem possible that a fall took place at this point during he 
highest stage of Lake Algonquin. It is, therefore, held that the
