A dark figure in Coconino County, Arizona

It was a Sunday afternoon in late June 2016. I was camped in a developed USFS campground (CG) on the Coconino National Forest in central Arizona in the Mogollon Rim area. The CG is situated in an canyon within a mixed forest of spruce, fir, oak, aspen, and mainly Ponderosa pine. The cliff edge of the Rim is about 3/4 mile South of the CG. I was sitting in the shade and had just finished reading a work of fiction by James Patterson which had a strange ending. I was musing about the ending and just looking West across the CG when a very fast moving dark figure crossed the CG heading from North to South. My first thought was of a large kid on a bicycle as it was moving so fast on the in camp gravel road. But its' travel path was counter to the road. Then I realized what it was that I had seen. It was a very large Bigfoot. The sighting only lasted about three seconds and I was very lucky to have seen it at all. It crossed the CG in a shaded area and blended well into its' background but the meadow beyond it to the West was bathed in afternoon Sunlight and backlit the dark figure. It was about 125 yards from my viewpoint so facial detail was not clear. It ran with a slight forward cant to its' body. I noted that the head did not bob up and down like a human runners head at speed. The coat was almost black looking but with the back lighting I noticed a slight reddish tint to the figures profile as it passed by. I had not noticed its legs or arm movement. Later, I went over to where the figure had crossed. On the North side of the drainage area, there was an area of crushed grass near the beginning of the travel path. Then the figure had moved South across the in camp road and had gone into a depression in the high grass. There were other areas of crushed grass along its' suspected travel path. Also a crushed fern near the split rail fence that bordered the CG where I suspect it had stepped over, crossed the forest road, and went into thick timber. I believe the Earth depression and a row of large logs obscurred my view of its'legs as it passed by. I had only seen its' torso from the hips up but did note that the figure did not appear to have much of a neck, if any. The torso was very thick and I guessed it was a least twice the thickness of a human. It was a once in a lifetime event and as I said, I was very lucky to have seen the Sasquatch at all. Truly, an awesome event which I will carry in my minds eye forever.
