i will be traveling through Canada driving from anchorage to Seattle will i need passport or just my orders?

I take it your in the military. If so your orders and ID card is all that is required.

Driving across the border you do not need a passport yet. I would think that your orders would be proof enough of who you are.

Have you checked Alaska Ferries to Bellingham Washington ? Gas is allmost six dollars a gallon..

When my husband drives the Al-Can he's always needed his passport. Even though you don't need it yet, they give people a hard time when they don't have it. So might as well bring it if you have one.
