EVERETT, Wash. (AP) — Searchers have found the body of a 26-year-old man who died after falling 50 feet (15 meters) into a glacial hole in Washington state, officials said.

The Snohomish County Sheriff’s Office said Jake D. Robinson was climbing on a glacier in the Kololo Peaks in northwestern Washington on Saturday when he fell into the hole.

An autopsy showed Robinson died of blunt force trauma and drowning, The Daily Herald reported.

Robinson’s hiking partner activated an SOS device shortly after the accident, which prompted a search-and-rescue team to arrive on scene.

A helicopter crew lowered a rescuer into the hole, where Robinson was found dead.
