Text Description: Only sample of Jensen_Palisade-10 unit (what it is labelled as in Table 1 of Jensen and others, 2013). Sample found at one of three gullies that comprise Site D2 (Fig. 2, Jensen et al., 2013). It forms white, discontinuous mm-scale wisps within organic-rich silt directly below the ~1 m-thick middle peat (Figs. 2 and 3, Jensen et al. 2013 Matheus et al., 2003). Consists of thick walled pumice, tri-cuspate and bubble-walled shards. Mineralogy difficult to determine because of the large amount of detrital material in the small sample.
