Holocene paleolakes of Lake Canyon, Colorado Plateau: Paleoclimate and landscape response from sedimentology and allostratigraphy

Pederson, Joel L, Holocene paleolakes of Lake Canyon, Colorado Plateau: Paleoclimate and landscape response from sedimentology and allostratigraphy: .

Summary

Middle and late Holocene paleoclimate can be inferred from lake-level fluctuations recorded in the sediment of two, fresh, ground-water?controlled paleolakes in Lake Canyon, southeast Utah. The record from Lake Canyon contributes proxy climate data for the region as well as insight into climate controls on sedimentation. The paleolakes were formed immediately upcanyon of side-stream confluences where disproportionately large volumes of alluvium were focused into the bedrock canyon. Excellent exposure allows a depositional facies model to be developed and allostratigraphic units to be defined. A facies-based proxy for the past shoreline position is applied to the allostratigraphy and radiocarbon-based chronostratigraphy to produce a [...]
