EXAMINATION OF BULK SOIL/DETRITAL CHARCOAL AND AMS RADIOCARBON AGE DETERMINATION OF MATERIAL FROM SITES ALONG THE NORTH FORK MALHEUR RIVER, AGENCY VALLEY, OREGON

Author(s): Peter Kováčik

Year: 2015

Summary

Located below the Beulah Reservoir along the North Fork Malheur River, Agency Valley, Oregon, sites NFM1, NFM2, NFM3, and NFM4 represent pits excavated in gravely and fine-grained Holocene terraces (Tessa Harden, personal communication March, 2015). Excavations produced eight bulk soil and eight detrital charcoal samples for identification of charred floral remains suitable for AMS radiocarbon age determination (Tessa Harden, personal communication March, 2015). In addition, one bulk sample underwent microscopic charcoal recovery due to insufficient macroscopic charcoal. Following identification of recovered botanic

material and detrital charcoal, three charcoal samples and one microscopic charcoal sample were submitted for AMS radiocarbon analysis.
