SAMPLE INFO : UT1434
Sample ID:UT1434
Station ID:WM97-61
Latitude:58.7938
Longitude:-161.1875
Datum:NAD83
Sample Type 1:Tephra Fall
Text Description:
Collected from a 40-cm-thick bed. From Preece and others (2011): A faulted and folded tephra bed within glaciotectonized sediments underlying drift deposits (Kaufman and others, 2001; Kaufman, written comm. 25/7/1997). Note that footnote in Jensen and others (2013) mislabels this sample as UA1434.
