A bone fragment from the Folsom layer at the MacHaffie site (24JF4) was submitted for collagen recovery and an AMS radiocarbon date. After this analysis an additional bison bone fragment was submitted for subsequent collagen recovery and an AMS radiocarbon date. The MacHaffie site is situated on the western slopes of the Elkhorn Mountains in west-central Montana. Paleoindian sequences contained within floodplain alluvium include a Folsom deposit with an estimated age of 10,425 radiocarbon years...
AMS RADIOCARBON DATING OF BONE AND CHARCOAL FROM THE MACHAFFIE SITE (24JF4), WEST-CENTRAL, MONTANA (2009)
Bone and carbon-enriched sediments from the MacHaffie Site (24JF4) in west-central Montana were submitted for AMS radiocarbon dating.
POLLEN AND PHYTOLITH ANALYSIS AT THE MACHAFFIE PALEOINDIAN SITE (24JF4), WEST-CENTRAL MONTANA (1990)
A single stratigraphic column through sediments at the MacHaffie Site (24JF4) yielded both pollen and phytolith samples. Pollen and phytolith analyses were conducted for each stratum to identify elements of the local vegetation for description of both local vegetation and paleoenvironmental conditions at this site through out the approximately 9,400 years represented.
