It's been a long and lonely winter trek for a female wolf that separated from her pack in Yellowstone National Park five months ago.The Colorado Department of Wildlife says a global position satellite collar, worn by the wolf, has helped them track her epic five-state journey, which has apparently brought her to Colorado in search of a mate. It says the wolf's last known location in Eagle County, is about 450 miles from its origin. The DOW estimates, however, that she may have walked an estimated total of 1,000 miles.The 18-month-old female separated from her pack just north of the Yellowstone National Park boundary in September and traveled across five states, including Idaho, Wyoming, and Utah.It's not unusual for wolves to travel as far as 60 miles of their pack, but biologist have documented approximately 10 wolves since 1992 that have traveled more than 190 miles.
