The pond is still there.

The road that was supposed to cross it was never built.

The houses were built around it, and the neighborhood exists, and people live in it and presumably walk past the pond without thinking much about what is under the water.

This is not unusual.

Most places with deep archaeological significance look like ordinary ground — like any other Florida peat pond, like any other stretch of midwestern soil, like any other unremarkable patch of earth.

The depth of history in a place is not visible on the surface.
