“In the thick trees of the NW, i could see a plane being gone forever for sure.”
The Yukon is not the Pacific NW, it is sub-arctic tundra covered with scrawny black spruce trees and brush. You’d have to tie 5 or more black spruce together to make a Christmas tree. No, that plane is either part of a glacier or at the bottom of a lake.
I’ve driven the Yukon twice, yup, it’s rather barren in many places but not all. But yep, it’s likely that it’s buried in ice or at the bottom of a swamp/lake.
For anyone interested in a very nice long drive... The Alaskan Highway is NOT it. Boring endless nothing....
