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 blocky flow of dacite lava is present on the northeast flank of Aniakchak volcano (fig. 4 [in original text], included in unit Qbn). Compositional affinity of the lava with deposits on the caldera rim indicates that the flow likely postdates Aniakchak I. Dreher (2002, p. 17) reported Aniakchak II lithic breccia resting on the lava."
Neal and others (2001) also report a dacite lava flow (on northwest flank?).
