Jensen_2007_White_River_NorthJensen, B. J. L. 1880 known unit; 1470; Age is approximate. Mean age of 11 radiocarbon samples from beneath the northern lobe of the White River Ash, ranging from 1750-2005 yBP (from Lerbekmo and others 1975).50--This sample is an average composition calculated from analyses of multiple White River Ash north samples from different locations. Individual sample IDs (analyses of which contribute to the average tephra bed composition) are noted in the sample description.The composition reported was calculated from analyses of fourteen samples: UA1042, UA1043, UA1045, UA1121, UA1120, UT2006, UA1119, UA1247, UA1248, UA1249, UA1251, UA1252, UA1253, and UA1254.Jensen_2007_White_River_North_averageTephra FallCumulateGlass 73.71 0.21 14.5 1.66 0.06 0.36 1.9 4.09 3.18 Reported standard deviation of zero. 10011191EMP1.66Cl=0.33; H2O=2.39EMP
