Coarse clastic members share a similar depositional history and mineralogical components with some variation due to changes in depositional environment, system energy, and clastic provenance. Coarse clastics consist of black to multicolored gravels and granules with black to white interstitial sands; lithic rich framework clasts of black to multicolored cherts with subsidiary mineral grains and lithics consisting of clear to white quartz and translucent to opaque white, gray, and yellow feldspar plus scattered clasts of ironstone, jasper chalcedony, and trace polycrystalline yellow metaseds. Gravels and sands are commonly clay mineral encrusted with occasional pyrite inclusion and subhedral crystal surface growth. Diverse non‐marine clast/grain surface features ranging from grind abrasion, transportation polish, impact chatter/frost on lithics and feldspars to mild aqueous solution frost on quartz. Clast/grain encrustation increase in grain packed channels then presents as freshly polished surfaces in clay held over‐bank deposits. The more massive bedded cohesive mudstone holds local sand packages, and a diversity of large lightly altered to partially carbonized tree wood fragments retaining their plant structures, brown black lignites, pyritized herbaceous plant remains, thin to thick walled shell fragments, and local volcanic ash fall beds. Volcanic ash falls are as local well defined beds and disseminated into mudstone host to create a very reactive and expansive clay. Mudstone/Claystone predominates from 122’ to ~270’ with conglomeritic sands predominating from ~270’ to ~815’.
