It's the nature of the wolf to travel. By age two, wolves of both sexes usually leave their birth packs and strike out on their own, sometimes covering hundreds of miles as they search for mates and new territory. Whatever the reason, when wolves move, they do it with intent—and quickly.
In Oregon, that male met another long-distance traveler from Idaho, a silver-gray female. This wolf had been collared by Idaho state biologists, who knew her as B300. She was born to the Timberline Pack, north of Idaho City, and it's possible to trace her ancestry back to the state's formal wolf reintroduction in 1996.
