A backpacker hiking in a "remote" spot at a Michigan national park has died after experiencing a "sudden onset" medical emergency, authorities said.

The 37-year-old woman was hiking on Monday, Aug. 12, with her partner near Isle Royale National Park's Lake LeSage when she "experienced sudden onset medical complications," according to a news release from the National Park Service.

A park ranger told NBC News that the small crew remained with them overnight because a larger crew was needed to transport the woman's body back to the mainland.

PEOPLE did not immediately reach Isle Royale National Park personnel for comment.

Isle Royale is located in a remote area of northern Lake Superior, and according to the NPS, it "preserves and protects the natural, cultural, and wilderness resources of a Lake Superior freshwater archipelago."
