MACROFLORAL IDENTIFICATION, MICROCHARCOAL EXTRACTION, AND AMS RADIOCARBON AGE DETERMINATION OF BULK SEDIMENT SAMPLES FROM THE 45TH AVENUE PROJECT, LOS ANGELES, CALIFORNIA

Author(s): Peter Kováčik; Linda Scott Cummings

Year: 2016

Summary

The 45th Avenue project site (Avenue 45th) is located on the southwest corner of Lincoln Avenue and Avenue 45 in Los Angeles, California. Four soil samples, collected from a boring and a trench in lacustrine deposits, were submitted for macrofloral analysis to recover and identify charred floral remains suitable for AMS radiocarbon age determination. Three samples from B-4 with expected dates between 15,000 and 6,000 years BP (John Helms, personal communication June 15, 2015) and one sample from ST-1 were submitted for radiocarbon analysis.
