Where is swauk pass on the Washington pass?

Answer 1

Washington Pass is on SR 20 also known as the North Cascade Hiway. SR 20 runs East - West through the Cascade Mountain Range between the towns of Sedro Woolley (to the west of Washington Pass) and Winthrop (to the east of Washington Pass) in WA.

Swauk Pass was the name originally given to what it now known as Blewett Pass. Blewett Pass was about 5 miles west of Swauk Pass. Over time the route over Swauk Pass became the primary route over and the name of Blewett Pass was applied to what had originally been Swauk Pass. The name Old Blewett was applied to what was the original Blewett Pass. This is located on US 97 between Ellensburg (to the South of the passes) and the towns of Peshastin, Leavenworth and Cashmere, (to the North of the passes).
