Text Description: Sample ID WL4C-2. Tephra sample from 286 cm depth in core. Four-to-six-cm-thick, dense, brown, silt layer that exhibits high MS. Difficult to identify tephra in the core stratigraphies because it is dispersed within the upper portion of a clay unit that is about 10 cm thick. References: ![]() ![]() |
