I was up again at daybreak and had a quick breakfast and headed out toward Ottertrack Lake for a long day trip of exploring. A short distance to the east of my campsite I took the 5 rod portage into the main body of Knife Lake on the Canadian border and proceeded north east to the 5 rod portage into Ottertrack. I paddled northeast on Ottertrack to explore the lake and then backtracked to the 20 rod portage into Amoeber lake. I now backtracked south through Amoeber lake to the 75 rod portage into Knife Lake. I them traveled south through a bay of Knife Lake to the 30 rod portage into the South Arm of Knife Lake. (This was the same portage I crossed this morning after leaving my campsite. I then proceeded west to return to my campsite for my last night on Knife Lake.
