5) Shale, gray to bluish greenish gray, 4to5=1"
v.f. sandstone bands, 10'
6) Sandstone, Orange brown weathering, fine quartz
sand size with CaCO3 cement. @ few wood
fragments. The lower 1' of this unit is
light green gray weathering, sand size,
same; difference seems to be the amount
of lim oxide with the CaCO3 cement.
8'
7) Shale, greenish gray, a few 1" of sand gritstone
lignite. (7/16/57/3) 21'
8) Sandstone, orange brown weathering, v.f. sand size,
much silt -> 30% ; brachiopods, wood, crinoid stems;
2 to 3" beds 3'
9) like 7 in lower part, gradually, upwards, the lithology
of unit 8 becomes dominant, beds 3" to 4" in the
sandstone: 46'
10) Sandstone, light brown weathering, (3' of
gradational beds at base to this unit into the
bluish shale at top of #11. 6" to 2" of bedding: 19'

11) Covered 23', probably blue gray shale with fine
limestone bed 8' thick, uneven nodular bedding surfaces,
swirls, byrgoons, crinoid back collections 7/16/57/6 -
12) Id., gray weathering, massive beds, blocks-
weather rounded, (not angular) This unit has
wavy bedding surfaces and seems to represent a large
fuzzy accumulation of dumped debris
6" to 8' beds, 7/16/57/4
32'
13) Covered 8' probably same as (#
14) Id., light brown weathering, cliff former,
21' to 15' beds, massive weathering across unit
across most of the ridge.
<3' to top of ridge.
