Isle Royale National Park hiker found "alive and alert" after being missing for a week

A hiker who had been missing since Sept. 5 from Isle Royale National Park on Lake Superior in Michigan was found a week later, the National Park Service said Saturday afternoon.

Officials said Craig Berg, 70, of Royal Oak, Michigan, was found on Sept. 12 by backpackers at the park and was reported to be "alive and alert." In a statement on Monday, Isle Royale park officials said the paddlers located Berg on Intermediate Lake. The National Park Service coordinated with the U.S. Coast Guard to rescue Berg, who was then transported to Marquette, Michigan, for medical treatment.

Federal officials said the Michigan Department of Natural Resources, Michigan State Police, Coast Guard and agencies from Minnesota and Wisconsin had been working with them to search for Berg.

"The successful outcome reflects the combined efforts of search teams, partner agencies and members of the public who assisted throughout the operation," Isle Royale park officials said.

"We are extremely grateful we were able to get Mr. Berg safely off the island and deliver him to the medical care he needed," Senior Chief Petty Officer Wendy Janson said in a news release.

Isle Royale is a remote island that's only accessible by ferry, seaplane or private watercraft, federal officials say. It has 165 miles of trails, 36 campgrounds and is open each year from April 16 through Oct. 31.
