Remembering Sunshine, 2 May 1972
May 2nd marks the 40th anniversary of the Sunshine Mine disaster. If memory serves, the Sunshine fire remains the worst hardrock disaster and one of the worst mining disasters in US mining since mine safety laws were put into place after 1779 men died in US mines in just 3 years (1907-1909). 91 people died in the Sunshine fire, including rescuers who succumbed to the smoke.
