Hyak is an unincorporated community located on Snoqualmie Pass in Kittitas County, Washington. It is located within the Snoqualmie Pass CDP. Hyak was established around 1915 at the eastern portal of the Snoqualmie Pass Milwaukee Road Railroadtunnel. Originally a train station, the community began to grow in the 1930s when the railroad built a world class ski area. Today there are approximately 200 full-time residences in Hyak and another 100 part-time. Hyak is a Chinook Jargon word meaning "hurry", "fast", or "swift".
In 1915, Hyak replaced Laconia as the main train station on Snoqualmie Pass. Hyak had a small school house, and a post office. The Milwaukee road built a ski area at Hyak originally known as The Snoqualmie Ski Bowl until World War II. After the war, it reopened as the Milwaukee Ski Bowl so it was not to be confused by The Snoqualmie Summit ski area located 2 miles north. A Class-A ski jump was built in 1941 and was said to be the largest ski jump in North America and held national championship events from 1941 until 1949 when the lodge was lost to fire. The train station saw its last train roll across its tracks in 1981 when the Milwaukee Road Railroad sold off the line and it was decommissioned. The old line is now part of the parks system called the Iron Horse State Park. The Hyak community still exists in the same area from which it started even though there is no train service. There is no longer a school and post office, but there are many more people living in the area today.
