Station ID:Jensen_Palisades_East
Latitude:65.1
Longitude:-153.19997
Datum:NAD83
Sample Type 1:Tephra Fall
Text Description:
The composition reported here is the average of analyses of five samples: UA1481, UA2084, UA2110, UA2162 (1), UA2164. Palisades-1, -2a/2b, -3, and -4, is found within multiple samples collected near river level at Site F, and in grab samples from Sites B2 and IB4 (see Fig. 2; Jensen and others, 2013); these are collectively termed the

Jensen_Palisades_East65.1-153.19997Jensen, 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 five samples: UA1481, UA2084, UA2110, UA2162 (1), UA2164.
