Mesozoic volcanic rocks, unit 1 (Coast Ranges) (Jurassic to Cretaceous) at surface, covers 4 % of this area. Until recently, the microblades from the Duncans Landing Rockshelter appeared to represent an anomalous situation in the local archaeological record. 10,500-8,500 CALYRBP) American Paleoarctic Tradition (APT) date to the Pleistocene/Holocene transition (Dixon 1999:165-192).

Kirk Peterson and Bruce Miller discovered two rubbing rock sites on the former shoreline of Lake Lahontan in northwestern Nevada (Peterson 2002). To the south, a late Holocene microblade industry was present in southern California, and is much better understood there (cf. (13)To date, I have located at least three archaeological sites along the survey transect where artifacts eroding from the coastal bluffs (from the subsoil at depths of 50-150 cm) appear to suggest a considerable antiquity (> middle Holocene?). They would have also found the Duncans Landing Rockshelter located nearby. And if this does not happen at Jasper Rock, perhaps it will at Mammoth Rocks.
