Report 70737: Heavy thuds and distinct rock clacking north of Teanaway Butte (Wenatchee NF)

I was hiking about 2-3 mile from our camp in Wenatchee National Forest and was sitting on a bluff that give an excellent view of the surrounding ridges. After a while of sitting and seeing nothing I hear a series of heavy sounding thuds that sound like they were in the rhythm of a person walking. I had no idea what it was. I thought maybe it was a deer bouncing away buy it didn't quite sound right. The thuds were almost cartoonishly heavy and loud. Then about 5 minutes later I hear what sounds exactly like someone banging two rocks together. I was still deeply confused as to what the sound could be. It sounded like it was maybe 40 or 50 yards away just into the tree and brush, out of sight. I got up and grabbed my rifle and started down to where the sound was. When I was about 10 feet from the trees I had the sasquatch epiphany, so speak, realizing it might be sasquatch. Every hair on my body stood on end as I made my way immediately back to the top of the bluff. I was still hearing the rock banging so I grabbed two rocks and banged them 3 times back at it. There was a pause and then I heard three bangs back. I went back and fourth with this thing for about 10-15 minutes. It would mimmick the number of bangs I would do. I do 2 bangs it does 2 bangs. I do 4 bangs it does 4 bangs. I was far too freaked out at this point two investigate further especially because it was getting dark. I made my way back to camp and shared the story. There's only one way to access that area and nobody else had been up there. My friends suggested maybe a bear was snapping it's jaws but there was a nearby gut pile from a deer my brother had shot earlier that day that was untouched. If a bear was in the area I would think if would have investigated the guts. Later I had my dad stand about as far away from me as I thought the sounds were and had him bang two rocks. It sounded exactly the same. I'm not sure what it could have been other than a sasquatch. We were the only people camping up that road.
