Cutbank exposes layers of mud intercalated with layers/lenses of debris flow and bedded sand and silt, overlying hyperconcentrated sand flow deposit. Section was remobilized rapidly from primary ignimbrite, but no primary ignimbrite is seen here. Exposed thickness > 4 m. Grey muddy facies has pumice scattered to 1.5 cm. Lithics mostly andesite-dacite lava to 1 cm, but include minor Jn and pyrite-bearing altered lava. Pumice clasts: mostly white pumice
