Lake Telmen is a saline  (presently 4 g l-1) closed-basin lake and is therefore sensitive to changes in  effective moisture balance. Between 7110 and 6260 cal yr ago, conditions in the  Lake Telmen region were hyperarid and a small saline (approximately 20 g l-1)  lake was present. Increased effective moisture balance but still arid conditions  prevailed between 6260 and 4390 cal yr ago. Since 4390 cal yr ago, generally  more humid conditions prevailed in the Lake Telmen region. As the lake deepened,  a hypoxic hypolimnion became established below a well-developed summer thermocline  resulting in varved sediment accumulation since 4390 cal yr ago. Between about  2710 and 1260 cal yr ago, a greater than present-day effective moisture balance  is recorded by a series of four lake highstand terraces. Sedimentologic profiles  from lacustrine cores suggest an increase in effective moisture during the past  approximately 680 cal yr.","author":null,"citation":"Peck, J.A., P. Khosbayar. 2002.
