Seen one preparing to cross the route 89 north from Flagstaff to the reservation one summer evening, right after sundown. The "creature," was standing very still near a tree trunk trying not to be noticed. Jet black, 8 to 10 feet tall, and at first I thought it was a horses tail blowing in the light mountain breeze so I slowed down, and turned on my halogen full beam lights. Then, thought is this a bear, but realized it was standing to up and was too tall to be a bear! When I scanned down again, I noticed huge dark skinned colored fingers under the jet black 5 to 10 inch strands of of matted shiny hair! I could not see the feet, since the grass was knee high, but the upper body was clearly displayed. I even was able to see the huge fit body and enormous upper body muscles on the arms, like it could scale a 45 degree wooded mountain or kill a deer by running it down and breaking its neck for food. As I got closer, I realized the enormous size and strength this creature had, and its intelligence to using the dark to hide in plain view! I freaked out and took off on 89 North near the Volcano national park turn off near by. This happened before the two road 89 was made, when it was a single two-way single road going North from Flagstaff, during a drought season in the summer. This creature was more thinking being and less ape animal to me, that was more reason to take off down the road. This area is known for deer crossing, so that is why I think it frequents this area waiting for prey. It could not have grew this large, and maintained the strength it had eating nuts or plant life alone, it needed a high protein source, like deer or other large mammal! The creature I saw was not like the famous California film reel creature, but very fit, tall, and looked more like a male, with its face covered in long hair. I guess it pushed its hair over it face to hide its eyes and to better hide in plain view. I was lucky to see this creature, since it blended in so well in the dark, and near the tree trunks while it stood still. The only reason I seen it was the slight curve in the road and the headlights of the car hitting directly on the creature and the trees. When the wind or breeze blew, it moved the tall grass and hair, but not the fingers and then I thought it was a horse's tail or a large mammal of some type. Then I just blasted the road with my high beam lights, and there it was in plain view. A vehicle was behind me and coming both 100 yards or more. I am usually cautious in this area since I don't want to hit a crossing deer.
