An autopsy found that Bryant died of cardiac arrest due to cold water exposure.
Deputies and medics responded to the scene, along the south fork of the Skykomish River near Boulder Drop, east of Gold Bar, at about 3:45 p.m. Sunday after receiving a report of a rafter being given CPR after falling into the river.
Snohomish County sheriff's spokesman Lt. Rob Palmer said the man had been with a group rafting the river with a commercial company based out of Peshastin. The man was reportedly wearing appropriate gear, including a personal flotation vest and helmet.
The CPR efforts were unsuccessful, and the man died at the scene.
