Summary: Oxygen-18 (d18O) values of sediment from the Wilson Creek Formation, Mono Basin, California,
indicate three scales of temporal variation (Dansgaard-Oeschger, Heinrich, and Milankovitch)
in the hydrologic balance of Mono Lake between 35,400 and 12,900 14C yr B.P.
During this interval, Mono Lake experienced four lowstands each lasting from 1000 to 2000 yr.
The youngest lowstand, which occurred between 15,500 and 14,000 14C yr B.P., was
nearly synchronous with a desiccation of Owens Lake, California.
Paleomagnetic secular variation (PSV) data indicate that three of four persistent lowstands
occurred at the same times as Heinrich events H1, H2, and H4.
d18O data indicate the two highest lake levels occurred ~18,000 and ~13,10014C yr B.P.,
corresponding to passages of the mean position of the polar jet stream over the Mono Basin.
Extremely low values of total inorganic carbon between 26,000 and 14,000 14C yr B.P.
indicate glacial activity, corresponding to a time when summer insolation was much reduced.
