Cause This disaster happened on May 1, 1910. This disaster was the deadliest avalanche in US history. The cause of the avalanche was thunder, rain, clear cutting, and fire The main reason for the avalanche was the rain, lightning/thunder which had an effect that had been set by the clear cutting of timber and by steam locomotive sparks, which cleared a pathway up the slopes above the tracks and created a perfect environment for slides to occur.. Lightning struck the side/slope of the mountain accompanied by the rumble of the thunder which created the massive avalanche. *Maya goes*The train rolled more than 1000 feet non stop down in the canyon 150 feet below, and engulfed underneath 40 feet into the snow, trees, and boulders. AfterThis caused other countructions of railroads near the cascades. An example is the same railroad that this disaster happened. Now there is massive concrete under and snow sheds over the tracks. There is a 7.8 mile tunnel built on the lower elevation of the cascades. It was finished in 1929. DeadThe massive avalanche caused 96 people to die thankfully 23 people survived. There were 75 workers aboard sadly I do not know out of the 96 that died or the 23 that survived which were the workers and which were and which were the passengers, and 15 bodies were recovered out of the 96. * Loaf goes*Interview”At 12:05 I woke up and saw a flash of lightning zigzag across the sky, and saw another, and then there was a loud clap of thunder. The next thing I knew I heard somebody yelling. We got up and climbed down on the bank to where the trains had been knocked by the slide … I saw a man lying on the snow and I went and got him, and put him on my back … and while I started up the hill, another snow slide hit and knocked me down underneath it, and I lost this man, I was sort of dazed and was underneath the snow some ten or 15 feet. I started to dig and climb out along the side of a tree, and finally got out, and I was in such a dazed condition that I walked down and walked into the river up to my shoulders, when I came to and realized what I had done.”— William Edward Flannery, Great Northern Railroad telegraph operator This quote shows what happened to the train from an insider point of view or an inside of the train point of view which describes how confused and shaken he was when it all took place. He survived but was still scared beyond death which can almost relate to when the passengers tumbled down thousands of feet. This man was a survivor of this tragedy. After No-OffAfter this tragedy there is a symbol a Iron Goat a name of a nearby hiking trail.
