The biker was deep in the steep hills and woods of Annadel State Park in Santa Rosa when he crashed. A 911 call went out and the Sheriff’s Office helicopter Henry 1 was dispatched to assist the biker.

A crew member was lowered into the woods, who evaluated the unidentified biker’s condition. It was determined he had suffered a knee injury that would require an airlift.

The biker was placed into a Bauman Bag-type helicopter stretcher, then flown to a Sonoma County Fire rescue vehicle for transport to a local hospital.

His condition was not released on Sunday.
