The Monte Azul archaeological site is located in the inter-Andean Aburrá Valley of the upper Medellín River in Colombia and it is dated from the Middle Ceramic period to the Republican period. In this study area, it is common to find evidence of disturbed soils that is related to ancient use and erosion. In Monte Azul, the pedogenesis is associated with the presence of fast-weathering eolian volcanic ash deposits, extreme acidity, low base saturation, strong leaching, high precipitation, and high temperature; hence, some of these tropical conditions are responsible for the low conservation of the archaeological record. Consequently, we used a geoarchaeological approach with paleoenvironmental, sedimentary, geochemical, and soil micromorphological proxies as integral units of analysis to understand site formation processes. Micromorphological and paleobotanical records indicate soil use dynamics and changes in paleoenvironmental conditions from humid conditions to small and persistent clearings around a domestic unit. This approach sheds light on the development of possible pre-Hispanic activity areas and cultivation techniques related to the ancient use of the Ferrería pottery style in the Central Mountain Range of Colombia.
