HH-62-228	67.46	-139.9	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).	Big Bluff section of the Old Crow Lowlands, located along the Porcupine River in the Yukon Territory. The bluff is 55 m high and made up mostly of fluvial and lacustrine sediments. Station ID is from Hughes (1972); radiocarbon dates and magnetic polarity sequence reported in Pearce et al. (1982). Preece et al. (2011) also refer to this site as Ch'ijee's Bluff, Bluefish Basin.	The tephra occurs in cryogenically deformed, late-Pleistocene fluvial deposits located below the glaciolacustrine silt and clay that form a conspicuous, dark, recessive unit close to the top of the bluff. Tephra has reworked thickness of 5 to 10 cm and occurs within fine-grained, peaty floodplain deposits. Tephra continuity is disrupted by large ice-wedge casts whose infilling commonly contains small pockets of the tephra (See Figs. 4B and 5 in Westgate and others, 1983). Channel gravel and sand underlie the tephra-bearing sediments and these in turn unconformably overlie fluvial and lacustrine sediments of probable middle or early Pleistocene age (Pearce and others, 1982).
