Managing Environmental Challenges with Anthropogenic Bedrock Modification: Archaeological Survey Evidence from the Upper Basin (USA) and the Island of Kos (Greece)

Human-environmental interaction studies typically focus on large-scale landscape modifications of vegetation or soils and rarely address smaller-scale human alterations to site settings. This approach is based on a broad concept of environment as “set” having spatially dispersed and regionally defined attributes, as opposed to something that is mutable at the scale of individual groups of humans living at a specific location. This paper examines how two prehistoric groups, the Final Neolithic to Early Bronze Age 2 occupants on the island of Kos, Greece and the Late Formative Period occupants in the Upper Basin, northern Arizona, selected and modified habitation locations involving exposed bedrock. Although chronologically separated by thousands of years and occupying different continents, these two groups share similarities in population size, socio-political complexity, and environmental challenges. In facing these challenges, both groups apply practical, but different, approaches that utilized one of the most prevalent globally available resources – limestone bedrock.
