Papilio machaon [or bairdii] ssp. oregonius
This is the Oregon Swallowtail. I consider it to be Papilio bairdii spp. oregonius, but many authors are now lumping it and calling it Papilio machaon ssp. oregonius. It differs from P. zelicaon in generally larger size, more pointed forewings, and much yellow on underside of abdomen, thorax, and head (mostly or entirely black in P. zelicaon). Also, the larval host plants are Artemisia (usually) rather than Umbillifers. This is the more common form in the desert canyons (and towns) of eastern Oregon and Washington, while P. zelicaon is seen near the coast and is more common in the mountains.

With so much black on the upper forewing
I think this is an Anise Swallowtail.

Compare:



Western Tiger's stripes (below) come further down the wing:

Do you know how to move images to the guide, yet?
These will be a nice addition.

Hit "tag all" under one of your images and you'll see they appear as thumbnails to the left of the BugGuide window. Navigate to the species image page - to make it easier, you can use this link. Click on "move tagged images" and you're done.
