A DNA test has confirmed that a lone gray wolf is roaming Arizona, just north of the Grand Canyon, a long way from its home in the northern Rockies. The animal, which is protected under the Endangered Species Act, is the first known gray wolf to visit Arizona in about 70 years. After repeated sightings of the wolf over the last month, the U.S. Fish and Wildlife Service (FWS) collected a sample of the animal's feces in Kaibab National Forest, near the north rim of the Grand Canyon. This means the wolf traveled at least 450 miles (725 kilometers) to get to northern Arizona.
