PORTLAND, Ore. (KOIN) — A climber was airlifted from Lewis and Clark State Park Sunday afternoon after he fell roughly 40 feet, according to the Multnomah County Sheriff’s Office.

Corbet Fire, which assisted at the scene along with Gresham Fire, said the man fell while rappelling. Rescue crews had to set up a rope system where they then lowered the man an estimated 450 feet from the bluff.

Authorities said the man was “alert and conscious” after the fall, but still needed medical attention.

Interstate-84’s Exit 18 was temporarily closed while LifeFlight was brought in to transport the climber to a nearby hospital. His exact condition is unknown at this time.
