This portage is shown on Fisher maps but not on McKenzie. To find the portage follow the stinky mud creek out of the most Western arm of Ross. Make enough noise to scare the moose away before you get to close. There is a exit from the creek on the left onto a 224 rod well maintained portage. It is harder to find the portage when going from Cullen to Ross. It is on the North side of the lake just before the most Eastern tip.
