CHEYENNE, Wyo. — The U.S. Fish and Wildlife Service wants people to report any more sightings of a black wolf that appears to have wandered hundreds of miles east of Yellowstone National Park.

An officer with the U.S. Department of Agriculture's Wildlife Services agency photographed the wolf not far from the Belle Ayre coal mine about 10 miles southeast of Gillette on Saturday.

The wolf wore a radio collar but whether the animal is male or female is unknown.

U.S. Fish and Wildlife Service Wyoming wolf recovery coordinator Mike Jimenez says anybody who sees the wolf should call him. He says if the wolf is causing problems, they should call Wildlife Services.

Yellowstone wolves seldom roam so far east, although a vehicle killed one in western South Dakota in 2006.
