Late Quaternary Zonation of Vegetation in the Eastern Grand Canyon
Cole KL. 1982. Late Quaternary Zonation of Vegetation in the Eastern Grand Canyon. Science. 217(4565):1142-1145
Plant fossils from 53 pack rat middens indicate which species were dominant through the last 24,000 years in eastern Grand Canyon. A latitudinal shift of climate is proposed to explain past vegetational patterns which cannot be explained by elevational displacement of present zones.
