Stevens County sheriff's deputies said the 36-year-old woman was attacked while jogging on a trial between Thomas and Gillette lakes.
The woman said when she drooped to the ground and got in fetal position, the bear batted at her then eventually left her alone.
The victim was treated at Mount Carmel Hospital in Colville for unknown injuries, then released.
Officials with the state Department of Fish and Wildlife are now searching for the bear with help from the U.S. Forest Service. They are setting bear traps and considering using dogs to help locate the animal.
Wildlife officials urge those who encounter a bear in the wild to follow the tips below:
• Don't run. Pick up small children, stand tall, wave your arms above your head and shout.
• Do not approach the animal and be sure to leave it an escape route. Try to get upwind of the bear so that it can identify you as a human and leave the area.
• Don't look the bear directly in the eye, as the animal may interpret this as a sign of aggression.
• If the animal does attack, fight back aggressively.
