We completed one of our deepest units this week, which closed out at approximately 3 meters in depth, before reaching culturally sterile soils. The unit has great stratigraphy, with visibly distinct occupation levels. Capitalizing on the great stratigraphy of this unit, we took our first column samples for future pollen, starch grain, and phytolith analyses. The goal of these samples is to document how Izapa’s land use and environment may have change throughout the different periods of the site’s occupation. Our column sampling methodology was developed based on the recommendations of Iran Rivera, director of the pollen laboratory at ENAH (Escuela Nacional de Antropología e Historia).
