I wonder what you saw that day Jerry. There are Jaguars in the American Southwest and there have been plenty of sightings of escaped exotic pets, legal and illegal, that have really confused people over the years, like monkeys and the like.
Those motion activated cameras that hunters use catch crazy stuff every once in a while.
We saw another huge cougar at Red Rocks, far to the right of the Brass Wall area, around the corner facing town. Sue was downhill from me and looks into some boulders and sees a dead sheep. As she is turning to tell me how stinky it was, I see a giant cougar come out from the other side of the same boulder she was looking under and bounds away up the hillside. Really close call.
