Travelling through that burn area is surreal. I think you will enjoy it. Prepare yourself to look for rock cairns and flagging tape for portage markers and always keep an open mind - you might have to make your own way. Dead standing trees in that area are falling all the time.
Enjoy the trout fishing (and eating) on Adventure. It was outstanding when we stayed there. That was the one lake in the burn that had some live trees and a couple decent campsites.
Wrist has fewer but BIG trout.
If no one told you where to catch the walleyes on Mex Hat send me a PM.
