beds loc. present. Bell has sent Chirophyks & ostracods to Peck. OK'd for Lower Cret. He, Bell has also had fossils in polished pebbles studied by P&S & report says Pennsylvanian - could be Minnekahta or correlative units in Bighorns or Hartville uplift. (Might be worth investigating whether these derived from ancestral Rockies - passed to Fountain correlatives - then in Jurassic uplifts to Morrison? and Lzkota.) Doubt direct derivation. Crowleys thesis based on gold in Newcastless & Lzkota coals is also subject to interps. other than one he favors of local derivation of Hills Inyzu Kara (+) from emergent Hills over near Keystone. Gzylzud mentioned work by Russians on transport & redeposition of gold in solution.) Approx succession, without regard to thickness, shown above for Gzulzads qezd.
