Site discussed: Toronto Lake. Lake is located about 80 km north of present treeline. Looked at O and C isotopes in organic matter and cellulose. Changes related to variations in productivity. Changes reflect closed basin and outflow conditions. Closed basin conditions correlated with intervals of warmer climate and treeline advance in mid-Holocene. (16/12/2007).
