I suppose Stumpy knows for sure, but I doubt there's much blow down from the July 4, 1999 storm in there.  There's some south of the Man Chain on Emerald and Carp, but I have not seen much evidence of blow down on the Man Chain itself.  I think it just skimmed the southern edge of Quetico and did not get that far north, at least not in a major way.  That's not to say there isn't downed timber from other events.
