8) Covered, 21' - shale?
9) Limestone, blocky - yellow-brown weathering, 6" to 1' beds, 2.5' to 3'? - Can't
see any rubble base, top is planar, but lacks lamella upper 2' or 3'. Shell hash.

{note: illustration:
bed 6: 163'
bed 7: 23'; 7/3/57/3
bed 8: 21'
bed 9: 2.5'; 7/3/57/4
bed 10: 2'
bed 11: 6/3/57/5

bed 14: 7/3/57/7}
10) Covered 2'
11) Limestone, same as 9, 8-12"
12) a) shale ? 6" to 1'
b) rubbly, conglomerative (1/2" to 1" pebbles) organic frag. Limestone 2' (silicified fossils common)
c) Limestone, coarse size organic frag. even top bedding surface 2'.
The beds above 12 form irregular steps on the dip slope to the NNW. Biohermal deposits cause the irregularity in the 6" to 2' beds - 15' to 20' of strike on the dip slope of this ridge which are above bed 12 and not covered by alluvium.

Fault strikes N15W - 25' strat displacement east apparently lowered. This fault is 100 yards +- east of section 5.
This afternoon I tried to traced bed 11, section IV around to section V. Bed 11 is eroded away about in line with place where the lower part of section gets mixed up at the first turn in Geol. Canyon. The upper surface of bed 11 is nearly completely covered with fusulines - The next lower limestone coquina in Section IV, bed 9, I don't believe has this great population of fusulines. After losing bed 11, I drop down to what I believe is bed 9, at least the stratigraphic interval is about right. Then to bed 8? back to 9? then a biohermal limestone, then a crinoidal limestone, finally to a limestone with a reasonable number of fusulines 11? About 300 yards from where I first lost 11. If this bed is #11 of section IV then it is about 15' to 20' higher with 2 additional limestones in between. Perhaps several more. (ie, a chert separating 2 from vuggy zones, capped by a limestone).
13) Covered 4'
14) Limestone, brown-yellow weathering, silicified fusulines and gastropods, some echinoid? spines.
