Lecture: Climate Change and Old Corn at Caņada Alamosa
7:00 pm – 8:00 pm
The Human Systems Research Lecture Series on the Archaeological Explorations of the Caņada Alamosa comes to the Museum on Oct. 10.
The title for this lecture, by Dr. Curtis A. Monger, is "Climate Change and Old Corn at Caņada Alamosa: 4,000 Years of Geomorphic and Isotopic Evidence.
The lecture is free.
The Caņada Alamosa Project in southwestern New Mexico, which produced a sequence of old corn beginning circa 4000 BP and continuing through the LateArchaic/Early Pithouse period, explored geomorphic deposits that begin in the late Pleistocene and continue to the recent historic period. Human populations at Caņada Alamosa reached their maximum during the period circa 600 to 1400 CE during which people advanced from pit house villages to large pueblos. Geomorphic evidence of climate change during this period was investigated using the model that increased aridity reduces vegetative cover and the resulting erosion and alluviation drives base level fluctuations of the Rio Alamosa valley floor, and terrace formation. These data, supported by a suite of 23 radiocarbon dates, are used to reconstruct the broad outlines of climate change in the Caņada Alamosa as well as provide comparison with other regions of the American Southwest.
Curtis Monger is the National Leader of Soil Survey Standards with USDA NRCS and Professor Emeritus at New Mexico State University where he taught Soil Classification, Soil Genesis, Intro Soils, and Intro Environ-mental Science. He received his B.Sc. degree (1981) in Plant and Soil
Science from the University of Tennessee after which he mapped soils for the Soil Conservation Service. He later received his M.Sc. degree (1986) in Geology from University of Tennessee, and his Ph.D. degree (1990) in Agronomy (Soil Science) from New Mexico State University. He is author or co-author of 45 journal articles and 24 book chapters on soil-geomorphic-ecological relationships, carbon
sequestration via carbonate biomineralization, and geoarcheology.
