## Where it stands

**Disputed** Two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Erosion is concentrated where the plateau's natural catchment entered the enclosure.
- Erosion features stop at the Khufu-period quarry boundary.

## What would rule it out

- Mapping showing the most eroded walls are not on the catchment's flow paths.
