Description: From Waythomas and Nye (2002): "These deposits [mid-Holocene pyroclastic flow and lahar deposits] are overlain by a several-meters-thick soils-tephra sequence. The buried soils are rich in organic materials, and the tephra consists of thin (less than 1-centimeter-thick), fine-grained volcanic-ash deposits that probably record small explosive eruptions of Crater Peak about 1,000 years ago (fig. 5 [in original text])."
