Context
immediately below the lowest ash layer, interpreted as Mazama tephra, 90-100 cm depth
Comments
DjPn-47: This is a deeply buried stratified site with an unidentified early mid-Holocene component beneath ash layers interpreted as Mazama tephra. Above the ash are Hanna, Pelican Lake and Late Prehistoric components. A radiocarbon date for the lowest component is somewhat younger than expected if the identification of Mazama tephra is correct.
