Locate a cat first, as close as you can, anyway. Tracks, sightings, kill, etc. Burn the gas into the snow, call wardens, loggers, forest service, etc.
If you're athelete enough, you can hump on a track in the snow and jump it. In this country you have to be in good shape, but it can be done.
Calling is a lot more commonly used method. Ecalls make it safer, and much easier to stay hidden. Using vocals help keep them from going stealth on you. Makes a big difference.
Good luck!
