Abstract
We have made isotopic and dendrochronologic measurements on material collected from the Two Creeks site. Radiocarbon dating of outside wood of four logs yielded an average of 11 760±100 BP, in good agreement with results of Broecker & Ferrand (1963) over 25 yr ago. The range of 11 640±160 to 11 900±160 BP suggests a period of forest growth of 200-300 yrs. Stable-carbon isotope chronologies on cellulose from 5-yr ring groups show δ13C scatter among trees typical of that found within modern sites, with some matches of isotopic maxima nd minima. Some downward δ13C trends may result from physiological response to rising lake levels (and/or cooling temperatures) at the site, which also produced very narrow rings in the outer ca 50±20 yrs. -from Authors
