My dad took me and my sister to a movie in 1974 or 1975 - he died in August 1975 - and we don't remember the name of the movie.  We have been looking for the movie for years, but without the title, it has been impossible.  I remember a few things vividly:  (1) the story was about a man - accused of a crime he didn't commit - goes into the mountains and is being hunted by agents; (2) in one scene, he puts on snow shoes and walks to the edge of a cliff in the snow making tracks to look like he fell off the side, then puts the snow shoes on backwards and retraces his steps; (3) the guy makes a raft, puts all of his belongings on the raft and covers it with a tarp and snow, then hides under the tarp and floats down the river right behind the agents - they don't realize it is him since he is disguised as an ice-flow.  If anyone could help with a movie title, I would really appreciate it.
