Beaver Lake is twelve miles in length and six in breadth.

The flat limestone country rises into bold rocks on its banks and at the mouth of the Ridge River the limestone discontinues.

The lake is very deep and has already been noticed for the number and excellence of its fish.

The Ridge River is rapid and shallow.

We had emerged from the muddy channels through an alluvial soil, and the primitive rocks interrupted our way with frequent portages through the whole route to Isle a la Crosse Lake.
