Ded people

It's not a matter of time it's a matter of intent

500 years

150-200 years

Until Indiana Jones shows up.

I’d say marked grave 250 years, mass graves 75 years.

One lifetime after their last line of descendants have died

When the archaeologists get there

actually there is a literal debate about this in the anthropology community. It boils down to there being people to complain about it when you do it mostly.

I'm just gonna have "please don't dig me up" written on the back of my gravestone in me native language and laugh as a ghost when the Dudes who obviously won't be able to read it get it translated after they already dug me up.
