A radio-collared wolf from the Snake River pack that spent several days in the Medical Springs area last week has crossed Brownlee Reservoir and entered Idaho.
The four-year-old male wolf, designated OR-18, apparently swam across the reservoir Thursday, said Brian Ratliff, district wildlife biologist at the Oregon Department of Fish and Wildlife's Baker City office.
Ratliff said signals from the wolf's collar showed the animal was in the Medical Springs area the afternoon of March 4.
Later that week the wolf traveled over Little Lookout and Big Lookout mountains, east of Baker City, then headed east down Connor Creek toward Brownlee, Ratliff said.
Ratliff said he was along the Snake River Road Thursday morning, at the mouth of Connor Creek, when he picked up the signal from the wolf's collar.
He didn't see the wolf, but by Thursday evening the signal showed the animal was in Idaho.
The wolf hadn't returned to Oregon as of this morning, Ratliff said.
Ratliff said he has not heard any reports of sightings or tracks associated with the pack of five wolves that have also been in Baker County over the past month.
None of those wolves has a tracking collar, although state officials hope to fit a collar to at least one of the wolves.
