Station: Palisades_Site_B

Station ID: Palisades_Site_B [1] [2] [3] [4]
Volcano:
Collector: Froese, D. G.
Date visited: 0000-00-00
NAD83 latitude: 65.09
NAD83 longitude: -153.25997
Default location: No
Location description: North-facing river-cut exposures on the Yukon River in Alaska about 70 km downstream of the village of Tanana. Site B at Palisades East is a series of shallow gullies emanating from the edge of a retrogressive thaw slump. Active slumping in 2005 exposed frozen sediments near Old Crow tephra, but most of the upper exposure was covered in 2007. The section is dominated by massive to weakly laminated silt, with rare beds of organic-rich silt and peat. Several tephra beds are present in the lower ~15 m of the exposure, but here we focus on the interval between 24 and 30 m above river level. Location imprecisely georeferenced from Figure 1 of Reyes et al. (2010).
