My vote too goes to White-tailed Ptarmigan. Yes, a white tail. Yes,
toes appear feathered (I enhanced and viewed on some of the best
equipment around). Very mottled with large white patches. The one
detail I'd expect to see in a Sprucey is a buff tipped tail - it is
usually very easy to see. Sprucey also "usually" have a fairly well
defined subocular white ring and a white ear patch. To me Spruce always
seemed to be a rather "neatly" patterned bird (barred NOT mottled) and
because of that my grouse vote would actually go to this bird being a
Blue over Spruce at that - though I'd give a 95% confidence to
White-tailed Ptarmigan. I spent significant time during a summer some
20 years ago observing all the birds mentioned above on an almost daily
basis so I'm fairly confident on this one. The 5200' elevation does not
seem out of line for a White-tailed hen with young in that part of the
Cascades.

(See the Audubon Handbook - Western Birds (Farrand) p 185 White-tailed
Ptarmigan...this bird could have posed for Daniel's picture)
