Histogram of the 2,859 calibrated radiocarbon ages (ka) in the midden database. The number above each bar indicates the number of midden-sample calibrated radiocarbon ages that fall within each 1-kyr age bin. Calibrated age data are from the CALIB704_CALENDAR_YR_BP_MEDIAN_PROBABILITY field in the AGEC14 table (Linked Table 3).
