Death Valley research revises age of last deep lake

Authors


Abstract

The last deep lake in Death Valley probably existed during marine isotope stage VI, more than 100,000 years earlier than previously thought, according to a paper presented this past spring at a conference on geologic research in Death Valley. The long accepted paradigm of a deep lake, known as Lake Manley in the very late Pleistocene appears to have fallen in light of recent U-series dating of high shorelines.

This and other new research were the topics of an interdisciplinary meeting on the “Status of Geologic Research and Mapping in Death Valley National Park.” As its title indicates, the conference was organized to compile up-to-date information on the status of geologic research and mapping in Death Valley National Park and surrounding areas. It also was intended to establish a network of active researchers to create synergy for cooperative, interdisciplinary research endeavors and to present recent and current research results in an informal setting, thus encouraging dialogue.
