An account of the Olympian Disaster can b found in my book, Montana Disasters, Floods, Fires and Other Catastrophes which is available at bookstores and libraries in many locations throughout the state or online.
Back in 1938, there wasn't the same kind of warning systems that we have in place today. When the railroad employee checked the tracks just hours before the disaster there was nothing to indicate that a storm was brewing upstream, intense enough to turn Custer Creek into a raging wall of water. We are lucky enough today to have easy access to National Weather Service Flash Flood warnings at our finger tips.
