I hate those category defying possibles. I've got a thing about fire reddened shallow bowls. There's also a few places near Stonelifter's stomping grounds which I'd hate to have him spot. He'd be very perplexed as to how the clams had managed to open in the way that would leave such weird marks.

Maybe the hole was made to take a pole for a banner - is that Rock Art ?
There's a not-cup right next to some CnRs at Dod Law fort which fits that description:http://www.themodernantiquarian.com/post/31577
It's the thing with the feather in it, and is about 4 inched deep. I'm not sure how drilled it is/was, but it'd hold a banner pole no bother.
