Abstract
The U. S. Geological Survey recovered eight sediment cores from beneath Clear Lake, Lake County, California, in 1973. The locations of the core sites are shown in fig. 1; lithologic descriptions of the cores, as well as radiographs, have been given by Sims and Rymer (1975a-g, 1976). A list of the procedures followed in sampling the cores and a list of the samples taken may be found in Beaver and others (1975); fish remains from two of the cores have been studied by Casteel and others (1975, 1977a,1977b). This report gives raw count data for 72 pollen samples from core 7, a 27.4-m long core from the southern or Highlands Arm of the lake (fig. 1).
Pollen counts for core 4, a 115-m core from the main basin of the lake, are given in Adam (1979); that core spans the time interval between the end of the penultimate glacial period, about 130,000 years ago, and the present.
