AIN 84-02 58 1 Band of concretions in cracked clay soil. Pierre shale, west of the shady soil continues to foot of next rise but no way of telling whether it is all Pierre or Benton faulted against Pierre 2 Shaly soil some bits of cone-in-cone and nondiagnostic concretions mixed with gravel 3 weathered patch of clay and bits siltstone + sandstone. 4 Looks like Glauconia 5 Typical Little-type sandstone. Fe specks, in place. 6 Outcrops of basal Morrison sandstone. " " " N 45 W 7 There is also a double SS here - exposures at it not carefully checked for this but it doesn't make much diff in drawing contact. Little balaena clots. West dot at Fe ss, thin - with Parcellinite Outcrop like zone above base. This bend sees S of School of Mines trench also. East dot on thin col above grey claystone may still be in Lytle or could be Glencairn-Lytle contact. Note- the Morrison west of it has fault in it just above 2nd ss from base. 8 Approximate Little Morrison contact. Here there is a bed of the parcellinite 2 foot thick also one on Rainbow CT sect this position 9 Approx. Lytle-Glencairn contact. Things are a sheared mess in here.
