While we're waiting for Bipto to get back on the previous request(s), the area (Rogers county, Oklahoma) we've had the most activity/sightings suggests there is a wide variance in physical characteristics of the UHS encountered.
Myself, and two other hunters encountered a tall (est. @ 7') individual with a rather thin body presentation. Mine was from a side profile view and to describe the facial features in terms that may be universally understood, he/she appeared as the GEICO caveman with the same descriptive observation from the other hunter that watched the UHS through his binos/scope for the better part of ~8 minutes. When I went to the spot of my observation, a footprint of ~16-18" was noted in the humus soil next to the blackjack post oak he/she had been beating upon with a club of ~4' in length.
Another UHS observed on multiple occasions by at least three HS's* was ~6' in height with a rather heavy set body build.
The apparent Alpha Male UHS observed by JW, TE & myself was estimated to have stood somewhere around 9-10" as the fork of the trees (where TE observed him in quad mode) later was measured at ~6' apart. JW's comment, after he observed him walking past at ~25 yards, was he would have dwarfed Shaquille O'Neal in body size presentation.
A photo, captured in 2009 on one of the gamecams interspersed throughout the property indicated a facial profile that, for lack of a better description, resembled Alley Oop from the old newspaper comics.
Then, when you throw in the "werewolf" incident, as reported by JS, it would appear to be a rather eclectic mix in that locale.
