| Location description: |
North-facing river-cut exposures on the Yukon River in Alaska about 70 km downstream of the village of Tanana. Site A at Palisades West is less than 30 m high and partially covered by willow thickets. From river level, a thick white tephra is visible across the top of exposure. The lowermost 16 m consist of massive and stratified sand and gravel, with one thin bed of laminated silt. A sharp contact separates these sediments from ~10 m of massive-to-faintly laminated tan/grey silt with thin, diffuse organic beds. Uppermost several metres of Site A sediments measured at three different sections. Location imprecisely georeferenced from Figure 1 of Reyes et al. (2010). |
