UA739	66.72	-148.45	Westgate, J. A.	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).	Road cut along the north side of the Fairbanks-Nenana Highway, 3 km east of Halfway House, exposes loess with paleosols and two tephra beds above weathered schist (see Fig. 8 in Westgate et al. 1983).	The lower tephra bed at this station is the Old Crow tephra; it contains few detrital contaminants, is about 30 cm thick, and is continuous across the l00-m-long exposure. The paleosols are weakly developed and comprise mere horizons of dark gray to black silt, 1-2 cm thick.
