Photos taken 33 years ago by a photographer who died in the Mt. St. Helens eruption have been discovered and developed.

Photos taken 33 years ago by a photographer who died in the Mt. St. Helens eruption have been discovered and developed.

Reid Blackburn took the photographs in April 1980 during a flight over the simmering volcano. When he got back to The Columbian studio, Blackburn set that roll of film aside. It was never developed. On May 18, 1980 — about five weeks later — Blackburn died in the volcanic blast that obliterated the mountain peak.

Those unprocessed black-and-white images spent the next three decades coiled inside that film canister. The Columbian’s photo assistant Linda Lutes recently discovered the roll in a studio storage box, and it was finally developed.
