About

About Cactus Hill

Sandy terrace site 1.2 km south of Nottoway River with buried A-horizon (Stratum E) with quartzite blades dated 18,000–15,000 BCE beneath Clovis. Joseph McAvoy excavated 1987–2001 after sand mining exposed dunes. Lower produced 25 blades, cores and hearth charcoal; upper Stratum B has Clovis points directly above without sterile separation — suggesting continuity vs bioturbation. One of Mid-Atlantic's strongest pre-Clovis stratified sand claims, with 2.2 m deep locus, buried A horizon and 0.8 m sand cap.

Why it mattersMid-Atlantic pre-Clovis sandy terrace with blade horizon directly below Clovis — tests stratification integrity.

Mysteries & theories

Mysteries

  1. 01Integrity of sand stratification — bioturbation vs intact horizon
  2. 02Age of lower blades — 16k vs 13k with OSL dating

Theories

  1. 01Clovis blades directly above pre-Clovis blade horizon — cultural continuity model
  2. 02Dune deflation as preservation mechanism for buried A horizon

Theories are interpretations, not findings. The seal above tells you how much scholarly weight the place carries.
