Description :
The semiarid landscape occupied by the Navajo and Hopi peoples on the Colorado Plateau is characterized by an extensive network of deeply incised arroyos. The AA. propose that climatic change, and more specifically, increases in precipitation, caused an acceleration in the erosion of the steep, typically minimally vegetated slopes of the Bidahochi Formation. Their interpretation differ from previous interpretations that emphasize the linkage of climatic changes, groundwater levels and arroyo incision. This study reveals the importance of integrating soil and ecologic studies with geomorphological research.
