A few hundred yards down a dirt path from Washington’s marble mausoleum at Mount Vernon you can find the unmarked grave where they threw the corpses of dead slaves.

Probably not even a hundred yards but yeah. I was there a couple times this past year and they were still doing excavations finding remains. Pretty wild
