Need Tips for Winter/Snow Trapping!

I am trying to figure out what works best when one has no dry dirt to set traps. I am not sure if snow would work all by itself. That is, set the trap on top of snow, pack snow underneath, and cover lightly with snow?
Thanks,
Chris
I am currently using dirt that is way to heavy/packy when wet, and the traps will not go off.

My best advise is to buy a FUR FISH AND GAME mag, go to the back page and order the coyote and predetor trapping video. I got them and they helped me the most. shows how to trap with snow and without. Also shows how to snare.

RiverRat,
Thanks so much for the tip! I'll do just that!
