English Lake Manly

Lake Manly was a pluvial lake in Death Valley, California, covering much of Death Valley with a surface area of 1,600 square kilometres (620 sq mi) during the so-called "Blackwelder stand". Water levels varied through its history, and the chronology is further complicated by active tectonic processes that have modified the elevations of the various shorelines of Lake Manly; during the Blackwelder stage they reached 47–90 metres (154–295 ft) above sea level. The lake received water mainly from the Amargosa River and at various points from the Mojave River and Owens River. The lake and its substantial catchment favoured the spread of a number of aquatic species, including some lizards, pupfish and springsnails. The lake probably supported a substantial ecosystem, and a number of diatoms developed there.

In Death Valley, lakes existed during different times in the geological past. After some poorly defined lake stages during the Miocene, Pliocene and early Pleistocene, the first large lake stage occurred about 185,000–128,000 years ago during the Tahoe glacial stage and formed the Blackwelder shorelines. This lake was the largest known Lake Manly; theories that the lake merged with Lake Mojave farther south or even overflowed into the Colorado River close to Ludlow and across several other basins are, however, questionable. After the drying of this lake a later lake stage occurred 35,000–10,000 years ago during the Tioga/Wisconsin glaciation; this lake was smaller than the Blackwelder lake. During the Holocene, the lake disappeared; today only ephemeral lakes occur in Death Valley during strong floods.

This lake is one among many major lakes that formed in the Great Basin, the best researched of which are Lake Lahontan and Lake Bonneville. Decreasing temperatures and thus decreased evaporation rates as well as increased precipitation rates during the ice ages were responsible for the formation of these lake systems. Lake Manly collected the overflow from a number of lakes including Lake Tecopa, Mono Lake, Owens Lake, Searles Lake, Lake Panamint, Lake Mojave, Lake Dumont and Lake Manix. Not all of them existed or drained into Lake Manly simultaneously.

German Lake Manly

Als Lake Manly wird ein prähistorischer See bezeichnet, der im Pleistozän das heutige Death Valley im US-Bundesstaat Kalifornien füllte. Zum Zeitpunkt der größten Ausdehnung vor 186.000 bis 128.000 Jahren erreichte er eine Länge von etwa 150 Kilometern und eine Tiefe von maximal 180 Metern.

Der See wurde zu Ehren von Williams L. Manly benannt, einem Teilnehmer des ersten Siedlerzuges von 1849 durch das Death Valley („Tal des Todes“), der die Region erkundete und vielen Mitgliedern der Reisegruppe das Leben rettete.

Der See trocknete noch vor Beginn des Holozäns aus, das Becken wurde seitdem im Rahmen von Klimaschwankungen mehrmals wieder teilweise gefüllt. Keiner der nachfolgenden Seen erreichte die Ausdehnung des Lake Manly. Bei der Verdunstung des Wassers fielen Mineralien aus, vor allem Salze, deren Ablagerungen heute den Talboden bedecken. Insbesondere gehen der Devil's Golf Course und Badwater auf den prähistorischen See zurück. Weitere Spuren des Sees können an den Talwänden gefunden werden: Auf der Höhe der ehemaligen Wasserspiegel sind an einigen Stellen terrassenförmige Stufen zu erkennen.

French Lac Manly

Le Lac Manly était un lac proglaciaire présent dans la Vallée de la Mort aux États-Unis, avant la désertification de la région. Ce lac disparut à cause de l'évaporation et de son isolement vis-à-vis du bassin hydrographique du fleuve Colorado. Aujourd'hui, le lac n'existe plus mais un grand aquifère se trouve dans le sous-sol
