This plateau slopes downward towards the southeast to a 
lower open rolling country completely and desolately burnt,* 
and paved titanically by granite boulders. In shallow valleys 
of this desert lie the lakes, — Middle Lake, surrounded by bog, 
as is the stream to Upper Long Lake, which is narrow and 
straight; Beaver Lake, irregular and desolate; Long Lake, 
remarkable for its straightness, and its extensions into others; 
Kennedy Lake, with its lower part in the unburnt country, 
and some others of minor prominence only partially shown 
by our map. The streams between these lakes run deep among 
huge boulders, which also form the shores, making them for- 
bidding of aspect and difficult of use for camping or any other 
purposes. While at first sight the lakes appear to bear no 
definite order, a closer inspection will show that they lie really 
in valleys having the Northwest Southeast directions character- 
istic of the ancient valleys of all this region. 
The Ottawa Branch I have not seen. It is said to include 
no real lakes, but a good many deadwaters and ponds, between 
which the stream is mostly rough. It is reckoned by the guides 
as the main stream, that from the lakes being considered .a 
branch. The combined streams are said to be rough down 
to the junction with the North Branch of Renous. 
Summarizing now the general physiographic condition 
of this region, it is evident that we are dealing with a part of 
the South eastern margin of the great central highlands, just 
where these highlands are sloping down to the lower country 
which extends eastward to the sea. This part of the highlands, 
moreover, is cut off from the rest by a great cross valley, — that 
largely upon it, whence it is also sometimes called the McLaughlm Branch. Lighthouse 
Mountain is so named because of a conspicuous bare place on its north side visible from a 
long distance. The most interesting name in the region is Shunabit Mountain, (also pro- 
nounced Shunabut and Shunabuck and written Shajiaput by Mr. Risteen), which I suspect 
to be Indian, though Mr. Braithwaite suggests a somewhat jocose origin in the opinion of 
lumbermen that it was a place to shun a bit. Jack's Mountain, was named for Edward Jack 
who conducted a survey of this vicinity. Five of the lakes, previously without recognized 
names, I have named myself. Young Bull for a superb young bull moose we saw there; Right- 
Angle Lake for a prominent characteristic; Middle Lake, for its position; .Arthur Lake for my 
companion; EffcOTr La/je for its shape. 
*This country has obviously been burnt twice. Mr. Mandeville tells me it was last 
burnt in August 190.5, and before that about thirty-five years ago.
