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°
