Lone wolf travels 3000 miles before being poisoned

In April 2009 wolf 314F was killed in northwest Colorado. She was a yearling from the Mill Creek Pack from an area just north of Yellowstone Park.

The image below depicts the route of her walkabout that covered about 3,000 miles according to a GIS analysis. She was outfitted with a satellite collar.

She was illegally poisoned with Compound 1080, a substance banned in Colorado.

Her journey demonstrates just how far wolves can travel, how much overlap there probably once was among wolf populations in North America, and why it is makes little sense to try to confine Mexican wolves to a relatively small area in Arizona and New Mexico.
