On October 14-19, 1990, the 6th International Conference on the Conservation of Earthen Architecture was held in Las Cruces, New Mexico. Sponsored by the GCI, the Museum of New Mexico State Monuments, ICCROM, CRATerre-EAG, and the National Park Service, under the aegis of US/ICOMOS, the event was organized to promote the exchange of ideas, techniques, and research findings on the conservation of earthen architecture. Presentations at the conference covered a diversity of subjects, including the historic traditions of earthen architecture, conservation and restoration, site preservation, studies in consolidation and seismic mitigation, and examinations of moisture problems, clay chemistry, and microstructures. In discussions that focused on the future, the application of modern technologies and materials to site conservation was urged, as was using scientific knowledge of existing structures in the creation of new, low-cost, earthen architecture housing.

The people who inhabited Southwest Europe from 30,000 to 13,000 years ago are often portrayed as big game hunters – and indeed, in some locations (Cantabrian Spain, the Pyrenees, the Dordogne) the archaeological record supports this interpretation. But in other places, notably Mediterranean Iberia, the inhabitants focused their hunting efforts on smaller game, such as rabbits, fish, and birds. Were they less effective hunters? Were these environments depleted of red deer and other large game? Or is this evidence of Paleolithic people’s adaptability? This volume explores these questions, along the way delving into the history of the “bigger equals better” assumption; optimal foraging theory and niche construction theory; and patterns of environmental and subsistence change across the Pleistocene-Holocene transition.
