Philippa,I think the 1949 Plane crash has the answer,Davids body was found below the area of the crash,he could have booked into the Clarance pubic house but instead inquired which way to the top of the Mountain?He fully intended to return,and had return tickets on his person,no other person met him on the Mountain so we keep delving for the answer,regards,John.
