Wiggle匹配的14 C测年法确定了一个82年的漂浮雪松树轮年表，从密西西比时期的一个土墩的基底层到公元1170 ± 9（1σ）（最外环）。虽然数值交叉匹配显示偏好的时间位置一致的14 C日期和视觉匹配，统计分数低于临界阈值每年交叉。边材校正终点后quem日期的材料，和他们的地层关系与覆盖日期，表明最早的截断土堆建设在4号丘发生在公元1177年之后。这个日期对于金凯过渡到主要区域中心的时间提供了信息，并且不支持早期的假设，即4号土墩是在早期金凯时代（公元1050-1150年）建造的。这些结果表明，考古收藏的潜力，以延长长树轮年表在美国中西部地区。
ABSTRACT Wiggle-matched 14C dates anchored an 82-year floating cedar tree-ring chronology from the basal layer of a Mississippian Period mound to AD 1170 ± 9 (1σ) (outermost ring). Although numerical cross-matching showed preference for a temporal placement consistent with the 14C dates and visual matching, statistical scores were below critical thresholds for annual crossdating. Sapwood-corrected terminus post quem dates for the material, and their stratigraphic relationship with overlying dates, show that the earliest truncate mound construction at Mound 4 occurred after AD 1177. This date is informative for the timing of the transition of Kincaid to a major regional center and does not support an earlier hypothesis that Mound 4 was constructed in Early Kincaid times (AD 1050–1150). These results demonstrate the potential for archaeological collections to extend long tree-ring chronologies in the Midwestern U.S.
