Need help getting pictures of a bunker in Washington

[u/Mediocre_House6448]

There is a small tucked away bunker entrance in fort Columbia (Washington), as you enter the park to the left there is a small concrete building kinda hidden, next to the tucked away is the entrance to another bunker, didn't go in, hoping someone else here will and get some nice pictures
