Man in Critical Condition After Bystanders Walking Along River Find Him ‘Pinned’ 15 Feet Down Crevice Near University of Oregon

A man has been rescued after being stuck inside a crevice in Eugene, Ore.

On Sunday, Jan. 18, the Eugene Springfield Fire Department revealed in a Facebook post that they had “an unusual rescue operation near the University of Oregon Sunday afternoon.”

ESF crews were called to a “possible cardiac arrest” in an area alongside the Willamette River diversion after people walking saw a person 10-15 feet “down a crevice” and called 911.

Officials added, “Arriving crews found an unresponsive individual pinned between a concrete diversion wall and large quarry stone.”

“Several crews with a total of 20 personnel responded for staffing and specialty equipment to aid in the rescue,” they continued.

The ESF did not identify the person, but noted that he was a male in his mid-30s. The victim was “transported in critical condition with a body temp of 76 degrees.”

The fire department thanked those who saw the man and called him in, adding, “If not for these attentive bystanders, the victim would not have survived much longer.”
