## Where it stands

**Most likely** Its tests partly supported it: three pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- Bedrock under the pit is cavernous Windsor Group gypsum or limestone.
- Other sinkholes exist on the island and nearby mainland.
- The pit fill is unsorted collapse material, not layered cut-and-fill.

## What would rule it out

- Excavation exposes vertical cut walls in till with tool marks and engineered platforms below the known searcher disturbance.
