Ancient pollen, fossilized beetles, and traces of long-vanished pastures are locked in the sediment of this shallow lake, perched in the Baghru mountain range 48 kilometers southeast of Ardabil in northwest Iran. The lake itself is unremarkable to a casual visitor -- a flat sheet of water covering 220 hectares, ringed by treeless steppe. But to paleoclimatologists and archaeologists, Neor is an open book written in mud.

Two fault zones, active since the Eocene period tens of millions of years ago, created the tectonic depression that holds the water. The Neor fault runs along the lake's length, and a second fault defines its western shore. T...

Rainbow trout fingerlings are introduced each year, and they thrive by feeding on Gammarus amphipods, small freshwater crustaceans that carpet the lake bed. The trout grow into robust, pink-fleshed fis...

Photo credit Elajan, CC BY-SA 4.0. The lake's greatest significance lies beneath its surface. Researchers extracted a 30-centimeter diameter core of peat from the northeastern corner of the lake bed and subjected it to pollen analysis and dating. The results revealed a 6,500-year-old sequence of pollen and beetle ...

The sediments record alternating wet and dry intervals that shaped human settlement patterns across the Iranian Plateau. W...
