SAMPLE INFO : UT1791
Sample ID:UT1791
Station ID:Sixtymile_River_1
Latitude:63.533
Longitude:-139.887
Datum:NAD83
Sample Type 1:Tephra Fall
Text Description:
Gold Run tephra occurs as white pods and lenses, up to 10 cm thick, in the upper part of a thick diamict, which is likely of colluvial origin. From Preece et al. (2011): 0.5 cm thick; pumice with rare blocky grains; in sand and silt; on strath 18 m above the Sixtymile River; 417 cm above top of bench gravel; field name JJO244.
