Weird patient position after injury

Patient found lying in snow with head tilted at awkward angle against small tree, after being struck by car and thrown pretty far, loss of consciousness. Good amount of bleeding from head. No way to communicate due to language barrier. I was stuck on best first action due to head injury and likely spine injuries and of course the freezing weather. Would you stabilize c spine as well as possible to reposition pt for scoop stretcher first? Take vitals first? Locate exact location of bleeding first? Thanks.
