This location has a brooding, mystical quality, and the native peoples would not have ignored it.
Why, thank you Dances with Wolves for notifying us of this remarkable archaeological discovery. I think I’ll head right up there to meditate on some crystals and burn some sage.
Okay, deep breaths....there, now I feel better.
Here's the thing - if a location contains no evidence of human activity, it is, by definition, not an archaeological site. It may have had cultural significance, it may be a place where people went to enjoy the ambiance, it may have been any number of things, and it may even be worth consideration when assessing the cultural resources in an area, but it is not an archaeological site (and in this case there is no evidence that any of the other things are true, either). If it's not an archaeological site, it should not be recorded as one. The record is muddled enough without people doing this sort of thing.
