Description: From Bacon and others (2014): "Two lava flows and several pyroclastic deposits are younger than the last major glacial advance but preceded the Aniakchak II caldera-forming eruption."

"A second precaldera silicic lava flow or dome is exposed in the cliff at the caldera rim north of The Gates (figs. 5Band 8A [in original text]; also included in unit Qbn in map figures). The rhyodacite composition of the lava is more differentiated than that of the northeast flank lava but is virtually identical to that of the overlying lower Black Nose Pumice, which suggests that the lava represents an early phase of the Black Nose Pumice eruption sequence. The lava appears to overlie Aniakchak I deposits."
