I went out to Boot last summer.  Jeff's map clarified the portage locations.  The Raja to Muskrat one was longer, but well marked & cleared.  The Muskrat end of that one was harder to locate on the return, since the sign had fallen. I missed it at first but luckily there was a large dam just a bit past it which I knew i hadn't gone over on the way out.  Muskrat to Bailey, and Bailey to Boot were shorter but rough & not well maintained.  I didn't go out to Richard due to my schedule.  The worst carry on the whole thing was the carry from Mole out to Raja: quite rough, with one esp. dicey bit where it went sidehill across a muddy slope with a drop to the creek, and then turned steeply uphill.  Raja was nice, except that as far as I could discover, there was no pit toilet.
