A good correspondence  between diatom-inferred salinity and historical records of mean annual  precipitation minus evapotranspiration (P-ET) strongly suggests that the sedimentary record from Moon Lake can be used to reconstruct past climatic conditions.  Century-scale analysis of the Holocene diatom record indicates four major hydrological periods: an early Holocene transition from an open freshwater system to a closed  saline system by 7300 BP, which corresponds with a transition from  spruce forest to deciduous parkland to prairie and indicates a  major shift from wet to dry climate; a mid-Holocene period of  high salinity from 7300 to 4700 BP, indicating low effective  moisture (P-ET); a transitional period of high salinity 4700  to 2200 BP, characterized by poor diatom preservation; and a  late Holocene period of variable lower salinity during the past 2,200 years, indicating fluctuations in effective moisture.","author":null,"citation":"Laird, K., S.C.
