Those 2 piece snowshoe frames. They seem to be more popular in Canada. In the US it is either the Maine or Michigan plus a few bear paws. On the Canadian 2 piece frame, the front is turned up a little higher than the Michigan or Maine style and it allows the wearer to sort of slide the shoe forward over the snow. I personally think it is a very good design. For some reason a lot of the NDN's up there decorate the tips with pom poms.
The walking backwards- I think that was the Mad Trapper of

, I can't recall. Charles Bronson played him in the movie.
The other thing is old fashioned logging skis. I saw them a lot in Vermont many years ago. Long, maybe 8 to 10' and 4" wide. Today's cross country skis. They require packed snow. In deep drifts they sort of turn over under your feet.
