Report 8948: In the early morning, hunter observes rock throwing near Valsetz

I was walking on a logging road, stopping to eat huckleberries. I heard some racket up behind me and thought it to be deer or elk, possibly a bear. Many of these species thrive in this area. I was very suprised to see the next thing that happened. Many large rocks were thrown in my direction. None that close though., rocks that weigh up to 10 pounds or more. This is the first I have spoken of this. It has been at least ten years now. I never saw anything but heard alot of noise above me. I was quite disturbed and thought maybe some pranksters were around. So for my safety I split.
