A falling tree left three people, including an infant, injured at Twin Falls State Park in North Bend Sunday morning.

Officials say a father, in his 30s, was in critical condition. His 16-month-old son, who was in a child carrier, was also in critical condition.

“The father took the child off the carrier and handed it over to a different person, who then ran to the trailhead to get it to aid immediately while they were calling 911,” said Dep. Daniel Arvidson of the King County Sheriff’s Office.

The boy's mother and sister were with them, as well as a family friend, but they were not hurt.

A woman in her 30s was also injured, but not as seriously. She was not there with the family but happened to be walking near them.

The rescue was about a mile from the Twin Falls Trail Head in North Bend. Arvidson said a volunteer rescuer told him a 20-foot section of a rotted out cedar broke off the rest of tree.

Witnesses say before the volunteer rescuers arrived, random strangers helped. An off-duty paramedic was nearby and helped before first responders arrived, said Dep. Arvidson.

David Klein and some of his friends pitched in, too.

“One of the firemen, he handed us a stretcher, a wheel, and a bracket and he said, ‘Just walk this up the trail to the first lookout point’,” explained Klein. “We gave it to the fireman and they escorted someone out of the woods.”

All three victims were taken to Harborview Medical Center.
