On the Border of Glacier National park
Near west Glacier….
Is that tall pole with the two plates on it, a snow depth indicator?
you see poles like that used a lot to mark the edge of the road or other structures near the road so snow plow drivers can navigate without going off the road or hitting anything when the snow is deep enough to obscure those items.
It looks to me as if there are a couple of traverse back-sights used by that guy doing videos while surveying in similar terrain.

That's some real 406.
