Eva_II	64.8516	-148.015	Preece, S. J.	124000 ± 10000 known unit; 10271; Age is approximate. Revised glass fission-track age with re-calibration; four Old Crow Tephra sample glass fission-track ages (UT1434, UT613, UT501, UT613).	Exposure on the west side of EVA Creek mining cut, Ester, Alaska; Gold Hill Loess overlies the Dawson Cut Formation and is unconformably covered by the interglacial Eva Forest Bed. Location coordinates from Preece et al. (2011); datum not specified, assumed to be NAD83.	Occurs as pods of tephra within the Upper Gold Hill Loess. Pods as thick as 18 cm, about 2.5 m above the Sheep Creek tephra and 1.5 m below Eva Forest Bed at this location. Sharp upper and lower contacts, 10YR7/1.
