Lake Tahoe basin climatic history reconciled with Fallen Leaf Lake sediment cores.
Cores have an unusually high quality, macrofossil 14C-derived age model.
Transition out of last glacial interval in Tahoe Basin occurs at ∼11.5 cal kyr BP.
Late Holocene neopluvial occurs from 4.17 to 3.65 cal kyr BP.
Climate state shifts at 3.65 cal kyr BP to increased aridity punctuated with high precipitation events.
