Abstract
Karlstrom used tree-ring data, archaeological deposits, and radiocarbon to date more than 40 stratigraphic sections to produce a detailed chronology of synchronous alluvial events for Black Mesa. His analysis reveals similar depositional histories in different drainage basins. The data also support the major postglacial drought of Antev's ending around 5000 BP that was followed by a wetter and cooler climate punctuated by secondary droughts. The valley bottom soils would have developed during drier periods with lower groundwater levels. Arroyo cutting results when there are lower groundwater levels and floods are confined to narrow, deep channels.
