This is the alpha female of the Canyon Pack. She has three pups, one black and two gray this year. They had just started swimming across the Yellowstone River when I saw them last about ten days ago.
Yellowstone Wolf Researcher, Doug Smith, likes to put radio collars on all the alpha wolves in Yellowstone. I fear that when I see this wolf next year, it will have a gross- looking radio collar around its neck.
Doug needs to leave these beautiful animals alone!
