This is an abandon snow shed that was built in 1914 to prevent snow and avalanches from immobilizing the trains, After one of the worst railroad tragedies in history, where 96 people died in two trains from an avalanche in 1910, the Great Northern Railroad decided it needed to put up more snow sheds. The new snow sheds would help protect this important stretch of track through the Cascade mountains that connected Seattle to the Midwest. But after an 8 mile tunnel was built through the Cascades that made travel to Seattle much easier, this line was abandon in 1929.
