BUTTE, Mont. -

State wildlife biologists are trying to figure out whether grizzly bears spotted this year in the Upper Big Hole River area for the first time in about a century came from Yellowstone or northern Montana.
   
Grizzly bear sightings have been confirmed on several occasions this summer in the Upper Big Hole River area -- for the first time in about a century.
   
Kevin Frey of Montana Fish, Wildlife and Parks confirmed photographs and tracks seen this summer are of a grizzly bear. He tells the Montana Standard that it's hard to say whether it is one bear or multiple bears.
   
Officials say the grizzly bear presence in the Big Hole is a sign of their overall population recovery.
