I got out last weekend to the general area I'd been poking about in. Nixed the atv rails-to-trails access point for another decommissioned railway leading into a nice boggy woodland after passing through a bit of blueberry barren. The beaver have dammed up the bridges-turned-culverts and raised the water up to the old rail road grade in places:
Passing one of the many interconnected boggy beaver ponds:
Another, with fresh lodge renovations:
Followed some Bobcat tracks for a while:
And in the barrens, a mysteriously appearing set of meadow vole tracks. I looked at these for a while trying to ascertain the critters arrival at this spot. It's not quite the vanishing BF trackway in snow but interesting to speculate an answer. There was no other sign of tracks anywhere, no lightly scuffed versions on crustier snow and no tunnels that the critter crawled up from, must be aliens:
I sliced out blocks with my knife surrounding the start point, expecting to see a tunnel, there wasn't one. ( I did fully encircle the entry point after this pic)
My only guess is when the snow fell it was about 15 degrees--light and fluffy. The tracks didn't look too old but the temp had risen to 32-33. Maybe the tunnel through fluffy snow had collapsed/compacted with the temperature upswing- IDK.
Yeah, unrelated to anything but observation/speculation... but I like doing that.
