A mountain resort at the north end of Keechelus Lake near the east portal of the abandoned Chicago, Milwaukee & St. Paul Railway tunnel in northwest Kittitas County. The station was named by railroad officials for the nearby creek and lake. Hyak is a Chinook jargon word used for “swift, fast, hurry” and generally refers to creeks that are swift running or bodies of water, such as lakes, connected to them. The tunnel is no longer used for railroad traffic but is part of Iron Horse State Park. Brave adventurers can walk or bike the 2.3 miles to the tunnel’s portal west of Snoqualmie Pass.
