I based my suggestion of "adult" on the illustrations in Sibley, which tend to be fairly accurate for other species. The pattern on the front of the neck in particular - buffy with a slight orangey or even ruddy tint higher up, dusky grayish below that - seems to be a much better match for his picture of a winter adult and for his picture of a first-winter bird (which looks much plainer). On several occasions, I also saw a two-angle structure to the crown, although this was generally smoothed out after a dive. Leaning more toward immature was the crescent behind the ear -- it was clearly visible at some angles (although never as white as the lower face), but hard to see at other angles. I agree there were some brownish tones on the upperparts, but, again, it's not obvious from Sibley that that indicates a young bird. Anyway, that's the extent of what I know or don't know about it.
