* Samples labeled "ave" are the averages of all fields of data for spatial replicates a, b, and c for that particular sample site. Spatial replicates consist of three samples collected within 5 to 10 meters of one another. † LR-04cX is an independently processes and measured laboratory replicate of LR-04c. § "in" in the terrace level field indicates that samples were collected between the second and third terrace levels. ¶ Age uncertainties include propagated analytic errors (1 sigma) in carrier addition and AMS measurement, and +/-10% (1 sigma) uncertainty in 10-Be production rate.
