Jensen_2007_White_River_EastJensen, B. J. L. 1250 known unit; 1470; Age is approximate. Mean age of 11 radiocarbon samples from beneath the eastern lobe of the White River Ash, ranging from 1175-1390 yBP (from Lerbekmo and others 1975).803--This sample is an average composition calculated from analyses of multiple White River Ash east 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 three samples: UA1044, UA1046, and UT1761.Jensen_2007_White_River_East_averageTephra FallCumulateGlass 74.52 0.18 14.15 1.4 0.05 0.3 1.68 4.03 3.36 Reported standard deviation of zero. 10011191EMP1.4Cl=0.34; H2O=2.57EMP
