The composition reported here is the average of analyses of two samples: UT1280 and UT1281. Occurs at elevations of 1-2 m above water level at west and east limits of Palisades East, but ~14 m above water level in the central bluff area. Occurs stratigraphically below the lower peat and is laterally more traceable than PA tephra samples.
The Palisades is a key reference site for the middle Pleistocene of eastern Beringia: new evidence from paleomagnetics and regional tephrostratigraphy

|Jensen_Palisades_East||65.1||-153.19997||Jensen, B. J. L.||The Palisades are on the south bank of the Yukon River in Nowitna National Wildlife Refuge, ~70 km downstream of Tanana village. Palisades East forms a heavily gullied, cliff-like exposure that is generally ~40-45 m in height, but ranges from ~25 m high at Site E to ~55-60 m high at Site D. It is difficult to access safely, with many near-vertical exposures and overhanging blocks of frozen sediment that frequently break free into the Yukon River. Location imprecisely georeferenced from Figure 1 in Jensen et al. (2013). Multiple sections were mapped and sampled across Palisades East: Site B1, B2, IB4, F, D1, and D2. See Jensen et al. (2013).||The composition reported here is the average of analyses of two samples: UT1280 and UT1281.
