Wolves don't like human footprints, but they'll follow snowshoe tracks, snowmobile tracks, sled tracks. They see footprints they gone though. I hung more snares yesterday, but I'm not expecting much til next week when the snow blends everything back in. I wiped out my tracks with a pine bough, but I won't be confident in the sets until snow obscures everything again.
Usually. Other times I've had them walk step for step in my boot tracks. Had one do that a couple weeks ago, had made a couple sets and brushed my tracks out, but didn't bother brushing them out walking down the skid road past them. Dang wolf walked step for step in my boot tracks for a couple hundred yards, the next day, even walked my brushed in tracks over to one set (snow set) but stayed back a couple feet and wouldn't step out on the blended in snow where the trap was. It was snowing when I set and there was about an inch of fresh, but boot tracks still looked pretty much like boot tracks. If I would have just shoved a trap in one of my boot tracks I would have had the dang thing.
I like to brush stuff out with a branch also, looks pretty obvious disturbance right then, but get an inch of snow over it and it really blends in. Best way I've found to blend in boot tracks naturally though is to run over them with a snowmachine if possible.
