Lust For Gold (1949) [Deputy Ray Covin]: William Prince is clinging desperately to the mountain top after fighting Will and as Will steps around a big boulder to kick him off, the rattlesnake on the boulder bites him in the neck, as he turns around it strikes him again and he staggers backwards and falls to his death. (Thanks to Brian)
