Context
Sample is from hearth located just in front of the wickiup doorway, meas. ca. 25 cm in dia. Given a credibility level of None because it is so modern. Another date is reported by Beta from the hearth but it was possibly contaminated by radioactivity from the atomic bomb testing in the atmosphere in the 1950s (B-132961).
