The Midcontinent of North America lacks robust terrestrial paleotemperature records for key Interglacials, limiting hydroclimatic insight. Here, we present a high-resolution MIS 5e (~132–121.5 ka) speleothem record from Crevice Cave, Missouri, using TEX86, Δ47–Δ48, and stable isotopes. Results show major hydroclimate shifts tied to orbital forcing and AMOC variability, highlighting continental hydroclimate sensitivity to global climate drivers.
