Portage Description:
The landing on the Jasper side was tough in the low water, but that was about the only difficulty.

Lake after portage: Ottertrack
Known campsites: not sure
Lake Description:
Ottertrack is beautiful. The only problem is there is one site on the Canadian side, and it is right near the portage from Jasper. The rest of the ~6 miles of the lake has no Quetico sites but plenty US sites.

Portage from Ottertrack into:
Knife via 3 unnamed lakes
Little Knife
Swamp Lake County
Return to Jasper
