Mono
Lake is one of a series of lakes in the Great Basin of the
western U.S. that shrunk drastically or completely dried
up since the glaciers retreated. Thus, the paleo-lake level
and sediment character hold much valuable paleoclimatic
information. The sediments are also excellent magnetic recorders,
providing a high-resolution record of geomagnetic secular
variation between 13 and 40 ka, including a large, rapid
excursion of the field.

precise stratigraphic markers in Mono and other nearby basins.
