On isolated Isle Royale National Park in the middle of Lake Superior, every trail is a remote trail.

Two campers were found dead at a remote campground in Michigan, National Park Service officials said on Tuesday, June 10.

According to a news release from the National Park Service, reports of two dead people found at a backcountry campground at Isle Royale National Park were called in at around 4 p.m. local time on Sunday, June 8.

Rangers hiked about 11 miles to the camping site and found both bodies. Officials said that both “ground and aviation resources” responded to the scene on Monday, June 9, to recover the bodies.

The cause of death is still undetermined, and both individuals have not been identified, but the investigation remains open, according to the park officials.

What to know about Isle Royale National Park

A remote island cluster located in Lake Superior, Michigan, the wilderness park is accessible only by ferry, boat or seaplane, and it is only open six months out of the year. The park is known for both its unique ecology and wildlife.

Park ranger Christopher Amidon told USA TODAY in 2023 that the park is known for two animal species that live in the park: Wolves and moose.

“There's been a wolf-moose predator-prey research study going on for over 60 years on Isle Royale, the longest predator-prey relationship study in existence,” Amidon said. “You have a really high likelihood of seeing moose while visiting Isle Royale, as opposed to wolves, which are incredibly secretive.”
