Window to the past. This idealized stratigraphy chart depicts more than 13,000 years of cultural deposits in two contiguous sections of a wall in a Wilson-Leonard excavation block. Top portion shows increasing use of stone cooking features (black dots indicate stones) in Late Paleoindian/Early Archaic times (stratigraphic units II and IIIa) and massive accumulation of burned rocks (middens) in later Archaic times, as hot-rock-cooking in earth ovens burgeoned. Bottom section shows the Leanne burial dug in from the Wilson soil (Unit Isi[c]). Wavy vertical lines indicate soil formation.
