Yellowstone Wolves

I wanted to see wolves so badly in the park and was beginning to get discouraged after catching up with Rick McIntyre of the wolf project when he told us that the signal of the alpha female of the Specimen's pack was lost. (this was by the bridge just before Slough Creek) We were on our way out of the park when we saw these two wolves trailing up the hillside. The gray was collared and the black was almost a chocolate brown if zoomed in. I'm not sure which pack these two were from.
