You have one species of Pogonomyrmex (salinus as P. owyheei; Cole 1968) which is wide spread throughout Washington. I agree with Lester that the ants you had were probably Camponotus.. Off hand I know of no sites which deal esp. with Washington ants, your best bet is going to be to try the various ant species and see what your HL thinks of them. Your second ant also sounds like a Camponotus. Camponotus and Formica are probably going the be the most common genera in your area, maybe Lasius as well. This link may help you some. Keep in mind that you may not find the exact species which occur in your area, but it will give you someplace to start. Get some pics posted or samples and Lester or I can probably help you.
