East of The Dalles, Oregon at the Blalock Canyon Exit.
I spent an hour and a half with the group. They seemed unaffected by me presence even though we came within 20 feet of one another in the end. They became really curious when I layer down on the ground to capture a lower vantages point, their eyes appeared puzzled and they strained their necks to look down at me from their higher vantage point.
One of the 10 Bighorn Rams that were grouped together I came across in the Central/Eastern edge of the Columbia River Gorge.
