Heading to the Spider Lake PMA in May. In my research I see the route recorded from Ima to Reflection is thru a boulder filled creek (might be called Sedative Creek). Is anyone aware of an old portage to bypass this boulder area? Renting a new Magic and thinking a carry would be better than trying to traverse the boulders. Thought there might be an old portage since there is an old established campsite on Sedative Lake.

Have you checked out the description on on bwcawild.com
