Dear Sitka Deer,
There is definitely a herd of wood buffalo in Alaska but I think they are being held in quarantine because of some legal hitch.
The ADF&G has a Wood buffalo Restoration Advisory Group in place. SCI is supporting this.
They are the largest land mammal in the northern hemisphere as far as I know.
I remember seeing photos of a jaguar from the American south-west but it had been cornered by dogs.
I have not see the trail cam of a black cougar but maybe someone got a picture.
The thing that makes me think it unlikely is that so many thousands have been shot in the last 400 years by hunters using dogs that you would think one would turn up someplace and I don't one ever has.
