Three climbers from Renton, Washington died over the weekend after falling during a climb in North Cascades National Park.

Personnel from the Okanogan County Sheriff’s Office and Okanogan County Search and Rescue volunteers responded to reports of a climbing accident near North Early Winters Spire, nearly 16 miles west of Mazama, Washington, at about 11:30 a.m. on Sunday.

The responders learned that a party of four climbers from Renton, which is a suburb of Seattle, were involved in a fall while descending a steep gully, the Okanogan County Sheriff’s Office said.

When crews arrived at the accident site, they found three of the climbers dead.
