170 9/6/58 - near Rand Leonard fm. Coll. 9/6/58/1 - found out about 550' above first S. characteristic appearance. (1) Strike Leonard - N70E dip 15NW The Leonard has 2 rather distinct facies although the contact between them is usually gradual. One is a silt + clay rich bed which weathers a mud brown gray. The other facies is a silt and yellow loam which the lo have been recrystallized + dolomitized into pattering coarse crystals. Both facies have to much a high %+ dolomite, but the "yellow" facies - extreme recrystallization is common. (2) Strike N85E, dip 3N Coll. 9/6/58/2 - 450' ? higher than #1 in Leonard. Just above massive ls. ledge (FB) on Kije map. Coll. 9/6/58/3 about 300yds west of coll.#1 and at about the same stratigraphic position. There are several fault zones seen in the lower cliff-ridge forming gravels from which Gs from field identification it would seem as if there be none Schwagerina species represent. Haymond anticline at Rand, Nebraska (1) dip 13S - strike N85E° - Haymond (2) K dips 20N (3) Gaytank Coyle 13S dip- (4) Haymond just beneath Charlie Hill dip 20 SW strike N65E° (5) Doctor's Hill - a well known fault on south-side is showing a rather smaller expansive. Strike N70E dip 60N The 1st cogs are gently turned against the face, and the fault runs NNE through the hill. The next fault enters strikes almost WSW and dips Sabout 85°
