The banding is fairly thick, not in thin layers like I've seen in gneissic banding. I've seen bands that were from 1 to maybe 5-6 inches thick.
I'm not sure the Pikes Peak batholith goes that far south but maybe it does. Or it could be a different but similar batholith.
PP granite is approx. 1 billion years old. Not that that has anything to do with anything, I just find that fact interesting.
Yes. The banding at Royal Gorge is very thick, almost and practically is migmatite (one step up from gneiss).
The granite is from the batholith, the gneiss is older and deeper than that and was exposed due to the carving into the Earth by the Arkansas River from the latest uplift of the Rockies.
I will look in my field book real quick to see what I have the date for for the gneiss and granite.
