What constitutes a alterna phase to me is a GBK that has either narrow bands of orange are pin stripers. Any pin striper from highway 277 or a hueco would be my example of a alterna. Speaking of which, I have never seen a blairs phase animal from the hueco mountains. Alterna phase animals seem to be more common in the western parts of alternas range.

A blairs phase animal is a GBK that has bigger bands of orange on their body. Everyone knows the classic example of a blairs phase animal (Langtry) so there is no need to even discuess further. Every region is going to have alterna phase and blairs phase animals.
