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 climate change throughout the course of the Holocene. This study has implications for the larger southwestern U.S. region and contributes to the broader understanding of desert (arid and semi-arid) climatic geomorphology. New ages for recent volcanics in the Red Hill–Quemado field have implications for recurrence interval calculations and evaluating the risk of future eruptions along the Jemez Lineament. The results of this study are also relevant to archaeological questions regarding how prehistoric groups responded to environmental change and to interpreting site distributions over the landscape.
While it is impossible to predict the exact nature and impact of global climate change on the American Southwest, many climate scientists predict…
