## 2. Investigate the central question

Compare mapped strata, rock ages, breccia characteristics and geophysical models. Require diagnostic impact evidence for an impact proposal and archaeological context for a city proposal. Separate intrusion age, uplift and later erosion. Consult newer phase-history studies before presenting one age as the whole structure’s date.

## 3. Compare explanations without merging evidence

Compare independent ages and structural models with observed rock relationships. Require impact-specific mineralogical and structural evidence and compare it with the intrusion model. Preserve contradictions and unsuccessful searches; proposed work remains unperformed.
