Snoqualmie Pass, in brief

Wikipedia doesn’t have a history of Snoqualmie Pass yet. The photos, dates and memories neighbors add here are how it gets written.

Snoqualmie Pass is a census-designated place (CDP) in Kittitas County, Washington, United States. It includes the unincorporated community of Hyak. As of the 2020 census, Snoqualmie Pass had a population of 372. The CDP is named for the mountain pass that carries Interstate 90 across the Cascade Range, which itself is named for the Snoqualmie tribe, a Native American tribe indigenous to the Snoqualmie Valley located west of the pass. The portion of the mountain pass west of the height of land, in King County, is not part of the Snoqualmie Pass CDP. Based on per capita income, Snoqualmie Pass ranks 8th of 522 areas in the state of Washington to be ranked. It is also the highest rank achieved…

Between the 2010 and 2020 censuses its population grew from 311 to 372 (+20%).
