Help building a wolf's den environment.

So for my first big encounter for my campaign I am looking to do a monster hunt for a solo class dire wolf. I got the special stats for the beast. Just need some good ideas for the environment.

So far I got:

Passive, scattered bones, any movement more then very close agility checks are needed.

Activate 1 fear. Den of wolves. Summon 1d3 minion wolf's.

What other tags or ideas could I do? I want stuff to show off the system to new players.
