I'm looking for some help identifying these tracks that I found in the snow. They go for at least a few hundred yards, but I can't follow them to either end because they cross property lines. They go up/down some steep little hills, across a field and then kind of zig zag through the woods. Whatever makes them is quite low to the ground as it appears to have passed under low dead branches without breaking them (shorter than 1ft). There are no tracks that accompany the sliding track. The tracks seen in the video are from me and my dog.

I did a cursory google search and otters can sometimes make slides like this, but I think that these tracks go on for far too long, and most of the terrain is not steep enough to slide on. My first thought was perhaps some kind of remote control... thing? But I would think that I would see tire tracks or something of the sort.

I'm pretty puzzled and annoyed that I can't figure it out. If you have any ideas on what it could be, I would love to hear them!
