Great Grey Owl

Great Grey Owl (most likely)
This owl swooped out ahead of the Jeep on a small dirt road in the woods near home.
We were driving right behind him, as he flew low to the ground. His wingspan easily 4+ feet his body the size of a big housecat.
We did not see his face. He was being chased by Ravens. He did come to rest here but WOULD NOT look at us. It could also be a very large barred owl.
Xtra: River from the house... still largely frozen...
