Witness accounts of the 1980 Mt. St. Helen’s blast indicate that the deadly ash and debris cloud that rushed down the slopes of the mountain were eerily silent. Dana Hunter recounts several survivors’ stories in her riveting post, The Cataclysm: “A Boiling Mass of Rock.” This vehicle was parked just 8.5 miles from the blast and shows the searing heat survivors endured.
