15．When Mount St．Helens broke out at 8：32a．m．on May 18，1980，Washington-based Bruce Nelson and Sue Ruff，both 22，were camping with four friends on the banks of the state's Green River--a probably safe 14miles north of the volcano eating marshmallows for breakfast．But the anger of St．Helens spared nothing in her reach，and within minutes nearly every tree in 15miles had been destroyed out of the ground．
Nelson and Ruff were blown into a deep hole left by a up-rooted tree．After the violent explosion ended，the couple hid under a pile of debris （殘�。� as huge ice pieces fell from the sky．Later，they heard two of their friends，Brian Thomas and Dan Balch，calling for help．Balch had been severely burned by a heat molten rock，which had melted the flesh off his arms，and he had no shoes．Thomas had been hit by a tree，which broke his back．Nelson and Ruff made a safe place for Thomas，walked Balch to the river，and then began walking through hot，knee-high ash to find help．
That night，they were found by emergency helicopters and rescued．Nelson argued with the National Guard pilot until he agreed to take him back up to the camp to get his friends．By then，Balch had been given an extra pair of shoes by a group of passing survivors and had walked out with them，and Thomas was later sent away by a small helicopter．Five days after the explosion，the police agreed to fly Nelson back up to his camp to look for his other two friends，Terry Crall and Karen Varner，who were still missing．He found them in their tent，Crall's arm wrapped protectively over Varner--both dead，with a tree on their bodies．
