For each foot of snow cleared, another foot fell.
On March 1, 1910, there were two Great Northern Railway trains stalled by heavy snow on Stevens Pass in Washington State, northeast of Seattle. A local passenger train was making the run from Spokane to Seattle; the other was a fast mail train from the east. They had arrived a few days before at the little railway town of Wellington, just on the west side of the pass. All the efforts of the railway to get them safely across the pass and off the mountain had failed. The snowplows were out of coal, the food was low, the snow was falling at one foot each hour, and a tremendous lightning storm had been raging for hours.
In the middle of the night, a massive avalanche came down and struck both trains. The force of the sliding ice and snow pushed the trains into the Tye River Valley, one hundred and fifty feet below.
