A hiker lost his footing and reportedly fell from a cliff down a steep flank of Hook Mountain in Nyack, New York on Monday afternoon and became wedged between a tree and the mountain face about 140 feet above sea level.

He managed to call for help on his cell phone while clinging to the tree, prompting a three hour rescue mission involving a stretcher and pulley system, according to ABC7.

The man, who has yet to be identified by authorities, fell around 12:30 p.m., and was lowered to the ground around 4:00 p.m by local firefighters and police. He was treated for hypothermia and shock on the scene, and transported to a local hospital with non-life-threatening hip and leg injuries.

"He told them [the rescue team] he was tired and in pain," Gordon Wren, the county's emergency coordinator, told the Journal News. "They said his speech was slurred. They estimated he was 140 to 150 feet above the river. He [had] no idea where he was."

Hook Mountain has the second-highest peak in the Palisades, over 700 feet above the Hudson.
