Identifying and explaining the end of long-lived practices is a major challenge for anthropological archaeology. We present a high-precision uranium series dating (230Th/U) chronology of an undocumented aspect of Hawaiian religion: the use of corals as offerings in gardens. Our results from the upland gardens of Kealakekua (Kona District, Hawai`i Island) document the onset of religious offerings at the same time as farming in the area at around AD 1400, with no samples dating to after around AD 1635. There are similar conspicuous endings to coral offerings in temple sites on the small, isolated island of Nihoa and in the uplands of Maui. On Nihoa, the lack of coral offerings after AD 1606 can be reasonably linked to the abandonment of permanent settlement on the island. In upland Maui temple sites, as is the case in the upland gardens of Kealakekua, the end of coral offerings around AD 1600–1700 suggests a disruption to a long-lived ritual tradition at a time when other metrics point to the rise of state authority over religion.

识别和解释长期实践的终结是人类学考古学的一项重大挑战。我们提出了高精度铀系列测年（230Th/U) 夏威夷宗教未记录方面的年表：在花园中使用珊瑚作为祭品。我们对 Kealakekua（夏威夷岛科纳区）高地花园的结果记录了公元 1400 年左右在该地区耕作的同时宗教祭品的开始，没有可追溯到公元 1635 年左右的样本。在孤立的 Nihoa 小岛和毛伊岛高地的寺庙遗址中，珊瑚供品的显着结局。在 Nihoa，公元 1606 年之后珊瑚供品的缺乏可以合理地与岛上永久定居点的放弃有关。在毛伊岛的高地寺庙遗址中，就像在 Kealakekua 的高地花园中一样，
