The tenderfoot was stupid. The Google map trail was probably old and petered out so he as a naive tenderfoot could no longer find it

Adding bogus streets and nonexistent towns to copyrighted maps is a long tradition...
Canada probably has the same roadless policy that Obama instituted in the Pacific Northwest. Except BC still has logging, so maybe not. Maybe it was just an abandoned logging trail.
