Blalock Canyon, East of Celilo Falls Native American Village.
These Bighorns run a large area in the rocks along I-84. They are seen quite regularly if you watch intensely to the hillsides between Celilo and the Blalock areas.
One of several Rams in the group. This one seemed to be the Boss of them all as he came down to separate me from the remainder of the group. He was the most friendly, and appeared to like having his picture taken, posing all the time to show his size and muscle. Without threat!
