Spatsizi Plateau Wilderness.
More than three words:
Egad- there is simply SO MUCH in B.C.!
I put Spatsizi on my life list after seeing an article, in National Geographic IIRC. It'll take some research to come up with a route, though. And the locals will laugh at you for doing it without a mule train. :o)
It's near the Stikine River, a river that nearly killed me, so maybe I have a bit of an attitude about the region.
