Text Description:	1- to 2-cm-thick pink tephra that occurred in a green silt slump one meter above the Fox Gravel, near the base of the Gold Hill Loess; sampled by Pewe in 1949, exposure is currently under water. Sample contains aggregates of fine-grained, colourless and brown glass shards poorly cemented by silica. Highly vesicular pumice is common with elongate vesicles, however, poorly vesicular pumice and bubblewall glass shards also common. Mineral component includes feldspar and FeTi oxides with accessory amounts of clinopyroxene, orthopyroxene, hornblende, and apatite.
