I watched a vidio of some guys hunting them in Kamchatka in the winter on Alpine snomachines with dogs, these bears were ALL +10' squared and BIGGER that they killed. That's a cool pic! A friend of mine Bob has his mounted like that in his living room, "Vaulted" cielings only. His is 10'3"sq.
Those all look like 11+ footers, that's 11 squared.
