Beautiful rock and Beautiful flutes, Jesse.
I would love to hear what it sounds like when one of those flute flakes is coming off.

What you were saying about the diamond shape of the preform is very helpful, makes a lot of sense,
and has got me thinking. (and that can be a dangerous thing

)
But what if the Guilford people were descendants of the Cumberland and they just stopped putting
the flutes in as time went on.
A time machine would certainly help. I could pick you up an hour ago.

Thanks for the pics, Awesome work,
Joe
