The white cascade

the long version

"In February 1910, a monstrous blizzard hit Washington State. High in the Cascade Mountains near the tiny town of Wellington, two trainloads of cold, hungry passengers and their crews found their railcars buried in rising drifts, parked precariously on the edge of a steep ravine. An army of the Great Northern Railroad's men worked round-the-clock to rescue the trains, but the storm was unrelenting. Suddenly the earth shifted and a colossal avalanche tumbled, sweeping the trains and their sleeping passengers over the steep slope and down the mountainside."--From source other than the Library of Congress
