Overwhelmed by discovering I could actually embed a photo in an email, I forgot to list COBIRDS as an intended addressee.

Here is a photo shared with me a while back by Norma Verhoeff taken by Norma at the Verhoeff Farm (private) between Lamar and Hasty (Bent County) just south of Highway 50 last spring. I believe this is a classic "blue" Ross's Goose. Thanks to Taylor for sharing his photo, which I agree with Nick Komar, is a hybrid Ross's X Cackling, and to Matt for sharing comments from BMRoss. It does seem odd that "blue" forms could be so common in Snow Geese and so incredibly rare in Ross's.

Ooops could have sworn Sterling had that labeled a Ross'
Here's some info I was sent back in 2014 from a birder in SD:
Story and photos: http://wildphotosphotography.com/WildPhotos/RossGoose/BMRoss.htm
And comment: "The dimorphism of Snow Geese is pretty well understood and is a result of a single gene locus where the dark allele is incompletely dominant to the light. In the Ross's Goose, it is not known whether there is a true blue morph or whether these birds are all hybrids or hybrid/backcrosses with blue morph Snow Geese."

Looks like the same type of bird that turned up at Sloan's Lake in 2014 (and spent some time at Wash Park ) that was deemed a hybrid (though some lucky birders got to count it as a Ross'!)
John Sterling found a 'true' blue-Ross' recently out in California:
