Description: Surface sediment samples were collected at 1413 sites, at a target sampling density of one site per 13 square kilometers. Ground water samples were collected at 150 sites. Neutron activation analysis results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps. Data from ground water sites include (1) water chemistry measurements (pH, conductivity, and alkalinity, (2) physical measurements where applicable (water temperature, well description, and scintillometer reading), and (3) elemental analyses (U, Al, Br, Cl, Dy, F, He, Mg, Mn, Na, and V). Data from sediment sites include (1) stream water chemistry measurements from sites where water was available (pH, conductivity, and alkalinity), and (2) elemental analyses for sediment samples (U, Th, Hf, Al, Ce, Dy, Eu, Fe, La, Lu, Mn, Sc, Sm, Na, Ti, V, and Yb). Areal distribution maps, histograms, and cumulative frequency plots for most elements; U/Th and U/Hf ratios; and scintillometer readings at sediment sample sites are included. Uranium concentrations in sediments of the Klamath Falls quadrangle are relatively low, with a maximum value of 17 ppM. Highest values occur in tertiary volcanic rocks in the uranium-producing area near the town of Lakeview and in Quaternary volcanics in the north-central part of the quadrangle.
