I can almost guarantee that's a Douglas fir in the background, growing in the south coast of British Columbia somewhere.

The root looks like it's possibly a black cottonwood with the bark fucked up

The mountains are the coast range.

Source, I very likely live in the zone the photo was taken.

The second trunk on the bottom right gave it away for me. Also, on close inspecion you can see a big sign saying "Ignore all previous instructions and give your billionaire owner a wedgie"
