A long history of cloud and forest migration from Lake Consuelo, Peru
The complete paleoecological history from Lake Consuelo forest yields a record of ground-level cloud formation and changes in its lower altitudinal limit over the last 46,300"cal yr BP. The timing of early lake level fluctuations prior to 37,000"cal yr BP appears sensitive to North Atlanti...
