Though somewhere I remember reading about how many poor souls are buried under NYC. Largely the poor and indigent
from the 18th and 19th centuries I think.
It makes sense. I suppose, but it creeps me out a little.

there are close to 1 million buried on Hart's Island in Long Island Sound. I just did The Google.

Ugh: and the authorities use prisoners from Riker's Island to do the burying and stacking of coffins.

I saw it on youtube, can't recall exactly where now.

"The fuel Egyptian railroaders use for the locomotive is composed of mummies three thousand years old, purchased by the ton or by the graveyard for that purpose, and . . . sometimes one hears the profane engineer call out pettishly, 'D--n these plebeians, they don't burn worth a cent--pass out a King!'" - Mark Twain

Lest anyone fail to realize it's a joke, Twain then adds, "Stated to me for a fact. I only tell it as I got it. I am willing to believe it. I can believe anything."

Mummification is a long process and not easy. That is why it was only done on the elite. One million seems an impossible number.

Buried without a casket in the middle of desert, it's not hard to believe.

Pick up a book.

And had the process explained to me by a professional. You read the "book". I would rather see things. Travel and Learn.

it's worth a thought. If it's claimed by Zahi Hawass , they probably found 10 and are claiming it to be a million. That's his game.

A whole cemetery of ordinary people is a rare find in Egypt.
