Hard to tell what it is other than some type of wild cat. The photo is at a bad angle for really telling. It doesn't have any spots but I suppose not all bobcats have the spots and their winter coat may be heavier.
Without having been there, it's really hard to say.
I think what CB saw that started this thread sure sounded like a cougar.
I've seen several bobcats in the wild but never seen a cougar in the wild only seen them in zoos (which always made me kind of sad as they should be out in the wild).
Regardless of what it is in the photo, it's a rare sighting and wish it was me who saw it.
