Other than 6 and 7 I would ignore the activity and walk away. I am not keen on telling others the rules. I think they already know them and are choosing to not follow.

I would stop and fully put out a fire - I have done that many times. And I generally pick up litter, if it is not too heavy or too much.

The mining part is a bit odd. If I saw that I might tell authorities where the activity was taking place when I got out. It is my understanding that mining claims are grandfathered. It would not be easy for me to tell if it was legal or illegal.

As for dogs- I have taken my dog where not allowed a few times.
