"From Kahshahpiwi northward, it looks like there is a swath of unburned land that will allow a passage to Keats. The only problem will be the 170m to Heronshaw and the nearby 160m to Metacryst. After that it looks like the 340m to the lake between Meta and Baird is unburned, the 190m to Baird looks iffy, but the 730 to Keats is unburned."

that was my route in reverse (after Keats and Sark that is) - it should all be passable now unless there is a big windstorm.  Unnamed to Baird, look for the tunnel I cut in that big windrow.  I cut detours around the blowdowns on the other portages.
