Summary
Hawaii Volcanoes National Park. Hiatus exposed in the north wall of Pauahi Crater: yellow tephra, which is a mixture of blocks and ash. This Tephra may consist in part of Uwekahuna Ash Member. Because it grades laterally into coarse debris in the crater of a buried tephra cone nearby, at least some of it may have been ejected from a local source. Organic ash is abundant atop the tephra, and the overlying lava flow contains many tree molds. Photo by J.D. Griggs, October 1985. Figure 12.27-B, U.S. Geological Survey Professional paper 1350.
