Completed our nineteen day trip on Sept. 11th.  Because of the route closures (one of which we informed of thirty minutes prior to flying out) we decided to stay in the N/E part of the park.  Flew into Artery and did side trips up into Ted's and west into Lower Artery and south into the south arm of Artery.  Paddled up the Bloodvein to Barclay and explored/fished there for three days.  Paddled up to Musclow with side trips into Hawk and north into the unnamed lakes until we could proceed no further.  Paddled Musclow in its entirety.  Active fires on the south shore of Barclay while we were there.  We could see the glow from the Manitoba fire at night from Artery.  (I think I saw a shadow of Marten roasting marshmallows?).  Fishing was fantastic even with fronts moving through.  Lots of wind on this trip.  My younger brothers first extended canoe trip (we have a new convert!).  Saw motor boats on Artery (from Lower Artery) and on Barclay (from Sobourin Lake Lodge).  No boats on Musclow.  No other canoeists seen on the trip.
An aside.....the fires seemed to be kind of "patchy" in the areas along the Bloodvein and on Barclay.  From the air however, there were large areas that had burned completely. 
Anyway, had a great time and already looking at the maps for next year!
Safe travels........Mike
