Hide in place

A sunny spring day made me head out to the wild after a long break. With the temperature just below freezing, there was a nice crust layer on the snow that carried my skis well. Even with a sledge in tow skiing was light and enjoyable.

I located a lonely birch tree at the swamp and dug up the bottom part of my hide and loaded the boards on the sledge:
I pulled the sledge to the same spot I have used for the last couple of springs, right were the black grouses have their mating season shows. To secure the hide in place, I made some "dead men" from branches and buried them under the snow:
When I was done, this is what the hide looked like:
Judging by the tracks in the snow, the hide is in a good place, there are tracks of grouses clashing just a few meters from the hide:
On the way back to the car, I spotted these tracks in the snow:
I won't tell who / what made the tracks just yet. Anybody want to take a guess?
