Impressive kit their Snowolf. Most impressive.
You board with that knife strapped to your arm? would get arrested here in Japan.
We don't have tree wells where I ride because the trees are different, even so going off piste solo is something I have stopped doing. As was mentioned staying in visual and verbal contact all the while is the way to go. Even if you just hit a tree or took a bad fall you could be in real trouble by yourself.
Stay safe people.
