how do archeological sites become so buried by earth over time?

271 views

I visited Butrint Archeological Site yesterday in southern Albania and saw that the ancient city is buried by at least 2 or 3 metres of earth, that archeologists are excavating to uncover the site.

What is the mechanism for these ancient cities becoming so buried in a relatively short amount of time?

It all depends on the local environment. Is it depositional, or erosional? Sediments can be deposited by wind or water, burying the ruin and thereby preserving it.

Erosional environments will ultimately erode the ruin along with surrounding materials, removing the room from the archaeological record.

There is a lot of survivor bias at work, here.

I have seen both types in action.
