Happy to, but how so?  The points in my comment are mostly taken from my reading of the archaeological literature on the mountain, or from my own too-brief visits to the quarry area over the years.  When I compare the archaeology of the mountain with the archaeology elsewhere in the islands, I'm drawing on my experience working as a Hawaiian archaeologist since 1968 on all the major islands save Ni`ihau.

That said, I'm happy to learn something new.
