N. South Dakota, Colbins slope on N.D. Section (set from Steve) S.E. of Bullhead. Molbridge member of Pierre: Dark calcareous clay shale. Weathers in chunky masses, bluish on fairly fresh slopes—goes to cluff on thorough weathering. Contains group of lenticites, Set of 3 in upper part: green-yellow-green, about 1" ± each and about 1½" apart. Baculites grouldis in shale. Some cone zones, upper one barren. Elk Butte member of Pierre Non calcareous clay shale weathering grey on slopes. Barren from cone in

upper part, No Bentonites. Elk Butte is not Pierre-Fox Hills transition members. Transition Beds, (60- Sandy shale with dark shale partings. Contact with Elk Butte member of Pierre marked by "yellow zone." yellow zone has sulphur colored streaks in blue-gray clay shale. Fossilferous conchs come in above yellow zone. Gemellia conchs with little spheres other ammonites etc come in above. Color of transition-definitely buff on weathering. Fresh exposures also buff colored due to sand content.

Colbries dope on Colgate-Cannonball section N. of Cannonball river, East of Brien. Colgate S.S. - 40 feet of typical Colgate exposed in cut of Cannonball river, Colgate-Hell Creek contact, - Bentonite on top of last Colgate sand, contains upright tree stumps. Lignitic shale, purplish overlies this setup with local disconformity. Hell Creek - includes 'morino' member near base. This consists of a buff glauconietic S.S. of F.H. Type bearing Halysacrites (Oysters in some

areas. Rest of Hell Creek consists of drab gray brown carbonaceous shales weathering light blue gray. These broken by thin zones of purple to black, small, very hard ironstone concretions. Shales include dinosaur bones, some poor lignite, no coal. (Differs quite a bit from Lance in lack of sandy beds + log concretions) Also differs from Hell Creek of Meade, Zebronch etc., counties in S.D.) Hell Creek - Ludlow contact. Drowned by Goblin at base of white massive yellow sand, 2-3 ft thick grading upward into yellow drab S.S. Above these come lignitic shales bearing F.O. flora. Coal beds present.

Cannonball:- Lower shale member and "greensand" members present in section. Shales grade into fossiliferous buff S.S. capped by eroded cone, layer. Greensand above has 2 barren cone, goes in it. Cones in this zone flat ellipsoidal 'alamasau' type common in upper Pierre + transition beds. Holomeraite in 'greensand'

North Dakota Stolles Long Lake - Linton Section on V.S. 83 + vicinity, (Not measured - see Stolles estimated general section.) Linton. Stream cut in Municipal Park exposes Pierre section. 50' ± of Elk Butte? Grey clay shale with 1 or 2 'yellow streaks' + possibly one or 2 bentonites, no concretions. Barren 10' ± Ruff locally shale, sand teds, + shale partings. Basal 2' = 'yellow zone' at Elk Butte - transition contact, 1½' above comes barren cone, zone of hard 'cold' ellipsoidal cones. 4 to 6 ft above cone zone of locally

reddish flaky cones, bearing Nicolleti. 25-30' - grass covered slope to base of 'white bed'. (Nicolleti zone may occur in this interval; one cone found on slope below 'yellow-zone'. On Rt 83 another found near 'yellow zone'. Neither definitely in place. Cones of flaky grey S.S. Shell hard black Calcareous core, Nicolleti + Menclaemensis? ) On U.S. 83 S. of Linton. section on grass slope above shows sandy shales weathering grey buff in lower 8". No concretions.

20' - White Bed. (Sampled) Porcellana very fine grained Dead white clayey substance. massive on fresh surface. Weathered surface shows cracking. Persistent in Linton area. Overlain by hard grey sandstone. N. of Linton, Pieced section shows cuff (greensand) now sand coming in over White bed. Also grey even bedded soft sands with local cockino. No marine fossils, no typical FH cones. Shells of cockino show reworking, This part of section resembles upper handled F.H.

Just south of Long Lake first out on U.S. 83 shows buff ss with great number of Holymotes. Position is stratigraphically below capping grey-white ss mentioned below. Top of section is hard persistent. (Say) grey white ss 2-3' thick capping levels east of road. Between this and top of White bed comes banded Fox Hills of 2 types. 1. Found about 10 feet above White bed is Grey + buff ss interbedded. Some coalines; No Guss, or marine fossils. 2. Banded F.H. Buff weathering

S.S., grey in places - buff to limestone shewline. Red weathering clusters of Halganits + red sandy zones cut sand at varying intervals. First cut S. of Long Lake contains great deal of vertebrate remains. Text list. Shark teeth Reptile teeth + bone frags ? Turtle frags Fish vertebrae
