SAMPLE INFO : UT1792
Sample ID:UT1792
Station ID:Sixtymile_River_1
Latitude:63.533
Longitude:-139.887
Datum:NAD83
Sample Type 1:Tephra Fall
 Text Description:
0.5 cm thick; pumice with rare blocky grains. Plagioclase, orthopyroxene, green amphibole, and Fe-Ti oxides as well as accessory minerals of basaltic hornblende and zircon.Occurs in sand and silt on strath 18 m above the Sixtymile River, 417 cm above top of bench gravel. Field name JJO244. Westgate and others (2011) revise the stratigraphy of the section that this sample was collected from and note that the sample UT1792 is located stratigraphically above Gold Run tephra (UT1791) at this section.

Sixtymile_River_1 63.533-139.887Westgate, J. A.2000-01-01 The Sixtymile River (1) site is in a placer mine excavation in terrace sediments 18 m above the Sixtymile River, Yukon Territory, Canada. Originally visited in 2000 by Jackson (2009); however, Westgate and others (2011) provide a revision of the tephrostratigraphy at this section after re-visiting in 2002. Coordinates from Preece et al. (2011). Datum not specified, assumed to be NAD83.0.5 cm thick; pumice with rare blocky grains.
