Glenwood Springs Post Independent: Collared wolves set loose in Grand and Summit counties as part of voter-approved reintroduction efforts in Colorado have traveled into Jackson, Routt and Eagle counties, according to a new map released Wednesday by Colorado Parks and Wildlife.

The map, posted on the agency’s website, uses Colorado watershed boundaries to indicate where wolves have been detected. It will be updated on the fourth Wednesday of every month.

The 10 wolves, which were captured in Oregon and released in December, have tracking collars that record their position once every four hours. Two other wolves that migrated to Colorado from Wyoming and were collared by CPW are also being tracked on the map.
