The Fajada solar markings are deliberate but the site was a sun shrine, not a precise calendar, and the lunar claims are unsupported.

**Most likely** Answers **1** questionPublished0

## Where it stands

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

## What it predicts

- The marker is less precise than horizon observation for anticipating the solstice.
- Historic Pueblo practice records sun-watching but not lunar standstill tracking.

## What would rule it out

- Evidence that Chacoans tracked the 18.6-year cycle, such as datable construction timed to standstill years.
