Off the Beaten Path

I did the traverse across the Big Raven Plateau in 2000 (I think, or maybe 2001).
First piece of advice: go, its amazing and unreal.
We scheduled 10 days for a a pretty leisurely pace. I think we did the last week of August, first week of September. We still had a few days where 2-3 cm's of snow fell, and it was below freezing every night.
We flew into Buckley Lake from Tatogga Lodge (on the highway, south of Iskut), and got picked up from Mowdade Lake (if you go in or out of Mowdade you may wish you brought hip waders...).
Due to high winds at the floatplane base, we were picked up two days after our scheduled exit date (of course, we had no idea why our pilot was not showing up, and we had to get creative with our remaining food rations...).
You could also consider doing the Spectrum Range (or combing it with the plateau, for a really long trek), by flying in or out of Little Ball Lake or Little Arctic Lake.
We got real up and close with a herd of Osborne Caribou, and had a couple of grizzly sightings (at a distance, binoculars are worthwhile). Did not see any other humans during our trip.
We looked for the hot springs that are supposed to be at Sezill Creek, but no success there.
I keep saying that I will go back. Been to Spatsizi as well, but if I was forced to pick it would be Edziza.
I saw "Colours of Edziza" a few weeks ago at VIMFF, and it rekindled my interest. There was a good article about a ski traverse of the park in Beautiful BC magazine a few years ago too.
Have fun (you will).
