Gold_Hill_III	64.9	-147.89997	Preece, S. J.	< 2020000 ± 140000 stratigraphy; 996; Weighted mean average of two dates obtained on sample UT497, which is stratigraphically below this sample (therefore this sample is younger). See Preece and others (1999) for methods.	Trench dug down to the cliff face on the north side of the Gold Hill mining cut, Fairbanks, Alaska; located approximately 30 m to the east of station Preece_1999_Gold_Hill_II. Location imprecisely georeferenced from Figure 4 in Preece et al. (1999).	Thin, discontinuous tephra bed about 4.5 m above tephra sample UT804 at this location. Coarse, white, wispy ash that occurs as small pods and stringers with sharp to diffuse contacts interbedded with silver (2.5Y6/2) silt with many charcoal flecks. Maximum thickness of 1 cm.
