96TOK163.198-142.178Schaefer, J. R. G.0000-00-00 Road-cut at mile 1284.6 of the Alaska Highway, southeast of Tok, Alaska. Approximately 17 miles east of Tetlin Junction and 100 miles north of Wrangell volcanic field. Twelve-m-thick section that exposes interbedded sands, silt and tephra that were deposited against a southeasterly sloping, highly weathered intrusive rock. The section is divided into six units based on lithology. Ten tephra samples were taken; however, approximately one m below tephra 96TOK1-9, there are wispy layers of several multiple-banded tephras that were very thin and discontinuous and not detailed in Schaefer (2002). Datum not specified, assumed to be NAD83. Collected from within the lower silty soil of stratigraphic Unit 3 at 96TOK-1 station. Stratigraphic Unit 3 consists of almost a meter of silt and sand. Highly vesicular pumice with an average grain size of 200 microns. 96TOK1-2Tephra FallCumulateGlass 72.52 0.18 14.88 0.41 1.94 4.69 3.33 Reported standard deviation of zero. 1003668EMP1.73Cl=0.34EMP
