Stratigraphy
| Stratigraphy comments: These deposits are correlated with the middle Pleistocene Lower Town Hill Formation, which at other sites have a radiometric age of ~405,000 years ago. This equates with the marine isotope stage 11 interglacial, which culminated in a rise in sea-level to > +20 m. |
