A French team of archaeologists have excavated the remains of a pre-Angkoran temple in the massive West Baray (reservoir) of Angkor.
A recent study published in the Proceedings of the National Academy of Sciences shed light on environmental factors that contributed to the collapse of Angkor in the 14th century. Periods of drought were inferred from a palaeoenvironmental study of the West Baray spanning 1,000 years, revealing a large amount of sedimentation (and thus water input) to the man-made lake prior to the 14th century, and much less sedimentation in the 14th and 15th century.
