A hiker died after he fell or collapsed near the top of the Bridal Veil Falls Trail close to Index in Snohomish County on Monday afternoon.

Medics, sent via SnoHawk 10 helicopter, did CPR on the 49-year-old man for about an hour but were not able to save him, said Courtney O’Keefe, a spokesperson for the Snohomish County Sheriff’s Office.

Other hikers had also attempted life-saving methods while waiting for emergency responders, she said.

O’Keefe said the man had been near the top of the trail when he fell or collapsed around 2 p.m. She said it was not yet known whether the man had suffered a medical incident.

The man’s identity and cause and manner of death will be released by the Snohomish County Medical Examiner’s Office.
