Location description: |
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). |
