I can still see the school being built and no evidence of the graves ever being revealed. Especially if there were no headstones. Grass grown over the grave sites.
I live in rural Florida now and I have seen things disappear over ten years on my own farm that the sandy soil just "absorbed" over time.
It's still not a stretch to see how this could have happened.
It’s actually quite sad.
So many forgotten people. Americans, who were born, had mothers and fathers that loved them, lived lives... all gone.
Just very saddening, to me.
Here in Northern California, every 6 foot or deeper new excavation requires the presence of a Native American representative on site to be certain that any bones or bone fragments found are not disturbed. Law on the books for twenty years or so. Local golf course rerouting drainage presently waiting for bone fragment analysis at a lab.
