ISLAND PARK — A man was attacked by a bear early Friday morning while jogging with his dog along the Aspen Loop Trail at Henrys Lake State Park.

The man was injured during the incident but was able to walk away from the encounter under his own power. His dog was uninjured and followed him out safely.

The man was taken by ambulance to Madison Memorial Hospital in Rexburg for treatment. His name and condition haven’t been released.

Idaho Fish and Game and Fremont County sheriff’s deputies moved quickly to secure the scene and launch an investigation, sweeping the park’s trail system and surrounding area from both the ground and the air, with help from the Sheriff’s Office drone.

Investigators located the site of the attack, but found no sign of any bears in the area.

Because the attack appeared to be a surprise encounter, and no bears were located nearby, officials said no further action is being taken against any specific animal at this time.

Henrys Lake State Park remains open for camping and boat launching. But after consulting with Fish and Game, park officials have closed the park’s trail system for one week as a precaution. Officials are asking visitors to respect the closure and stay off the trails until it’s deemed safe to reopen. Updates on the reopening are available by calling Henrys Lake State Park at 208-558-7532.

Fish and Game is using the incident as a reminder that all of the Island Park area is bear country.

“Bears can be anywhere,” officials said. “Assume their presence and always be bear aware.”

Officials shared a list of tips to help visitors stay safe in bear country:

• Always keep a safe distance from wildlife and never intentionally approach a bear.

• Stay alert for signs of bear activity, especially in areas with limited visibility or hearing, such as dense woods, bushy terrain or near streams.

• Travel in a group — groups tend to be noisier and less likely to surprise a bear.

• Make noise by talking or clapping, particularly in low-visibility areas.

• Carry bear spray somewhere accessible and know how to use it.

• Avoid traveling at night, dawn or dusk.

• Steer clear of carcass sites or signs of one, such as circling scavenger birds.

Anyone moving quickly through the backcountry — such as mountain bikers and trail runners — faces a higher risk of surprising a bear.
