Summary

The recognition of chronologically synchronous paleosols along the Cody Scarp in north Florida reflects broad patterns of deposition, pedogenesis, weathering, and climatic stability at the Pleistocene – Holocene transition. These paleosols, or stratigraphic "marker horizons," formed during rapid burial of A-horizons under mesic forest conditions. Marker horizons are best understood from the framework of genetic stratigraphy because they contain temporally diagnostic Early Archaic Bolen points. Since Florida notoriously lacks deeply stratified alluvial packages along major river drainages on the Atlantic Seaboard and west of the Appalachian Mountains, identifying chronologically specific horizons places relative sequences in Florida on much firmer chronological ground.
