17.) Sandstone, orange-brown weathering,
very silty, calcareous cement?
3"-6" beds
30' - stuff hard - rextallized, no fossils?
but fine crinital columns,
42'
18.) Limestone, gray/brown weathering,
1" to 3" beds, pock marked.
Wilt + f. calcareous foamed part.
[22" rextallized, fossil debris abundant]
[154' a 3" conglomerate bed, including
quartz, quartzite, chalcedony pebbles
to 1/2" diameters]
Afternoon looked at the rest of the
Leonard Fm., lower part of Wood Fm.
There isn't much difference between
the three facies and three upper
units here far east. King's Sect.
about 2 miles east is supposed to
be quite markedly different in the
2 facies of the Leonard Fm., but I
can't say that is true here.
from the top of these hills, one can see
beds in the Leonard Fm. thicken + thin
within short distances. The units
of brown-gray dolomitic ls. may change
from 120' to 0' thick in 300 yards.
Thus there seem to be few "key horizons"
in this interval - we have 3 or 4
clay pebble conglomerate zones near the top
of the Leonard, a couple of conglomerates in
the lower facies - and that is about all.
Even there are probably not of too great a
regional significance as they are mostly
3 to 6" cobbles. Lenses (near the top, th. f.),
at the once lower are calcirudites with
locally denuded pebbles + cobbling limestone.
clay frag. scattered throughout upper 150' 7/10/59
