Wellington (later known as Tye) was a small unincorporated railroad community in the northwest United States, on the Great Northern Railway in northeastern King County, Washington.
Founded in 1893, it was located in the Cascade Range at the west portal of the original Cascade Tunnel under Stevens Pass. It was the site of the 1910 Wellington avalanche, the deadliest in U.S. history, in which 96 people died<!--on March 1-->.

The Wellington avalanche was the deadliest avalanche in the history of the United States, marked by the total death count of 96. In the same month, the Great Northern Railway began construction of concrete snow sheds to shelter the nearby tracks. The depot was closed when the second Cascade Tunnel was completed in 1929; the town was then abandoned and it eventually burned.
Considered a ghost town, the old track and snow sheds remain and have been preserved as part of the Iron Goat Trail,
