Kalugin, I., Selegei, V., Goldberg, E. and Seret, G. 2005. Rhythmic fine-grained sediment deposition in Lake Teletskoye, Altai, Siberia, in relation to regional climate change. Quaternary International 136: 5-13.
Sediment cores from Lake Teletskoye in the Altai Mountains of Southern Siberia (51°42.90'N, 87°39.50'E) were analyzed to produce a multi-proxy climate record spanning the past 800 years. The Medieval Warm Period was identifed as a climatic period evidenced between the start of the authors' record in 1210 AD and ending around 1480 AD that was "warmer and more humid than today."
