b. How do depositional rates and periods of arroyo formation relate to climate change and associated changes in precipitation amount, seasonality, and intensity? c. How do the geomorphic histories of floodplains and alluvial fans compare? What is the explanation of any differences? 3. Consider the implications of the area’s geomorphic history for prehistoric maize agriculture and for the spatial distribution and surface visibility of archaeological sites (see Chapter 3 for specific research questions and preliminary findings). This dissertation fills a significant gap in our knowledge about the geomorphic history of west-central New Mexico. Perhaps more importantly, it documents the geomorphic responses of the Carrizo Wash watershed to…show more content…
Study of past geomorphic responses to similar climate changes can provide clues regarding how the region’s watersheds will be affected by ongoing global warming, making this study’s findings relevant to land managers. One weakness of the Intragovernmental Panel on Climate Change (IPCC) reports is a limited understanding of how modern societies can best adapt to rapid climate change (Van de Noort, 2011). Archaeology can contribute a broad-based understanding of the adaptive capacities and pathways of past communities faced with rapid climate change, as well as the possible cultural ramifications of various adaptive strategies. This insight is important for devising effective strategies for modern communities to successfully deal with the consequences of ongoing rapid climate change. An improved grasp of the interelationships between climate, geomorphology, and culture in the Carrizo Wash watershed can contribute to this larger understanding. Study Area: Carrizo Wash watershed, New Mexico, USA The Little Colorado River drainage basin is located in the southeastern portion of the Colorado Plateau physiographic province, an area characterized by broad plateaus and mesas, deep canyons, and gently dipping Paleozoic and Mesozoic sedimentary rocks with scattered bodies of volcanic rocks (Patton et al., 1991;
