Pisidiidae shell fragments (between 1 and 5) were crushed and treated with H2O2 for 30 min to remove organic material. The samples were then rinsed three times with deionized water. Aliquots (*100 lg) were weighed for isotopic analysis

Subsequent to*3,000 cal yr BP, Quartz Lake became a relatively closed system, with isotopic characteristics of progressively stronger evaporative influence

The cause of the transition to closed-basin conditions may have been geomorphic rather than climatic (but probably less important after 2ka)

The lake-water data from Quartz Lake indicate
evaporation during the ice-free season is a substantial
influence on the d18O values of water from the site
today. For instance, the d18O and dD values of the
surface-water samples fall on a regional evaporative
line (REL) with a slope of 4.94, deviating largely from
the GMWL (Fig. 2)
