Short summary
Between 4200 and 4000 cal yr BP, paleoecological evidence suggests a megadrought occurred in the central Rocky Mountains and western Great Plains. Modern climate analogues were used to explore potential climate mechanisms responsible for the ecological changes. Analogues illustrate that warm and dry conditions persisted through the growing season as a result of anomalously higher-than-normal heights centred over the Great Plains which suppressed moisture transport to the region.
