Landslide by Desmond Bagley

Action thriller by the classic adventure writer set in British Columbia. Bob Boyd is a geologist, as resilient as the British Columbia timber country where he works for the powerful Matterson Corporation. But his real name and his past are mysteries - wiped out by the accident that nearly killed him. Then Boyd reads a name that opens a door in his memory: Trinavant - and discovers that Bull Matterson and his son will do almost anything to keep the Trinavant family forgotten forever.
