## Where it stands

**Disputed** One piece of evidence for, three against. It needs two reviews to be accepted.

## What it predicts

- The bundles survived years in moving water with their rubber bands.
- The landing zone drained to the Columbia upstream of Tena Bar.
- The bills carry diatoms and sediment of a multi-year immersion.

## What would rule it out

- Rubber bands and bundles that fail within months in water, and a diatom assemblage showing a single short seasonal immersion.
