Interesting bird (not sure it is identifiable in thses pics - and location will only enable id through probability!) The lack of a flank patch seems to favour pacifica, but personally i can't rule out Great Northern (immer) from these pics - 1st pic looks very round headed, but am I imaging a peaked crown in the second!!

Which is why I wasn't going to use it to make one.

Meant to say, 'peaked forehead'. The 'chin strap' noticable in the first pick is not so obvious in the last, so may just be shadow?!?
So for this thread, why ask (although I understand that distribution for some id's is instrumental)? If it was a general comment to the poster about putting locations in the title then a single word post might not have been so helpful!

Can't see any reason to rule out arctica

The fact that the second pic almost suggests Great Northern yet the first pic shows it to definately be a Black-throated type suggests the latter for a start if the jizz differences between pacifica and arctica are consistent. Also the second and third pics do show a flank patch, so if they are all of the same bird, it is a Black-throated Diver arctica.

Funny thing is if I'd only been shown the first two pics and not known they were the same bird, I'd have had been leaning towards Pacific and Great Northern (albeit not making an identification on these grounds without better pics 
)!
