Temperatures had broken 90 degrees, the 31-year-old victim from Queens told police, when he stopped to get a drink of water on Henry Hudson Drive in Tenafly shortly before 2:30 p.m. Friday, Palisades Interstate Parkway Police Sgt. First Class Raymond Walter said.
"While doing so he lost his footing and fell," Walter said.
Parkway police climbed down "an extremely treacherous area of the cliff" and rendered first aid -- causing an injury to one of the officers, the sergeant said.
Members of the East Bergen Rappel Team got to the hiker and brought him up to the roadway before a unit from the Closter Volunteer Ambulance and Rescue Corps took him to Hackensack University Medical Center, he said.
The injured officer was taken to Englewood Hospital and Medical Center, Walters said.
Responders also included Alpine firefighters, Fort Lee police and EMS and an ALS unit from EHMC.
