May 2 marks the 40th anniversary of one of the worst mining disasters in U.S. history. In 1972, a fire broke out underground at the Sunshine Mine in Kellogg, Idaho; 91 men died of carbon monoxide poisoning. The disaster had a devastating effect on Kellogg and the nearby communities in Idaho’s Silver Valley. People who were there still vividly remember the events of that day. Producer Phyllis Silver talks with four people about their memories and how, in a couple of cases, it shaped the rest of their lives.
