I'm heading out to Blue Mountains,,,,any suggestions on what pass to take...90 to Yakima or White Pass...Chinook is closed

If you go 90, go all the way to Vantage & take a right on the other side of the bridge. Go to Othello take a right & wide on down to Pomeroy. That's the way I go but need a map to tell you the HWY numbers.

all dirt roads lead to pullman

I basically go the same way as KNOPHISH, just winding my way down there from Othello. If you go east on 26, you can take a right onto 260 at Washtucna, then a left onto 261, and that will take you across the Snake at Lyons Ferry and intersect with Highway 12 about halfway between Dayton and Pomeroy.

Definitely go Snoqualmie, as the others have said! Much, much quicker.
