Two localities are on a low terrace and their radio-metric ages of 120,000 ± 20,000 and ≥ 120,000 years B.P. suggest that this terrace is roughly contemporaneous with the Palos Verdes sand and correlative mainland terraces. One locality from a high terrace that contains an extinct faunal element yielded a significantly older age (>200,000 years B.P.). This content is PDF only. Please click on the PDF icon to access.
