ENDANGERED SPECIES -- Blue Mountains elk winter in the low open canyon slopes of Oregon, and the recent-arrival gray wolves figured that out fast.

These wolves made themselves at home on the open slopes in northeastern Oregon near Pendleton, where they've been feeding on elk, according to Dale Denney of Bearpaw Outfitters in Colville.

It's an exciting sight for some and an enraging sight for others.

Either way you look at it, it's humbling to watch this 40-second video clip of two wolves taking down an elk.
