Four hikers were rescued on Friday in Maine on Maine’s tallest mountain, according to officials.

Baxter State Park officials in Maine said the two groups of hikers got stranded on Thursday night after dark while on Knife Edge trail on Mount Katahdin, which reaches a maximum height of over 5,000 ft.

One of the hikers was a email in her 30’s and had an “unstable knee injury,” but the three other hikers weren’t injured.

“This incident started Thursday night after dark and appears to involve two different hiking parties that became stranded on the Knife Edge. One of the hikers, a female who is in her 30’s, has sustained an unstable knee injury. The other three hikers are not injured,” the state park wrote.
