in place. If the fusulines are Gaptank in age then I believe it is safe to consider
this outcrop in place. More than 5'. Collection 7/16/57/1 [Leonard Sch.
crastictoria] 1-64 C.R. check sample??
2) Covered 83'.
3) Shale, light gray (impart covered), 7 or 8-2" to 3" sand and silty sand (Quartz)
bands scattered in upper half of unit; 28'. 7/16/57/2.
4) Sandstone, orange-brown weathering, medium quartz sand, with silt
fragments of pebble (1/4 to 1/2" diameter) Brachiopods, crinoid stems, goniatites
wood fragments. 2'.
PG. 102
5) Shale, gray to bluish or greenish-gray, 4 or 5-1" very fine sandstone bands,
10'.
6) Sandstone, orange-brown weathering, fine quartz sand size with calcareous
cement. A few wood fragments. The lower 1' of this unit is light green-gray
weathering, sand size is the same, difference seems to be the amount of Iron
Oxide with the CaCO3 cement. 8'.
7) Shale, greenish-gray, a few 1/2" of sand of siltstone horizon. (7/16/57/3) 27'.
8) Sandstone, orange-brown weathering, very fine 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" is the sandstone: 46'.
10) Sandstone, light brown weathering, (3' of gradational beds at base to this
unit into the blue-gray shale at top of #11. 6" to 2' bedding: 19'.

11) Covered 23', probably blue-gray shale with possibly one limestone bed 8'
uneven nodular bedding surfaces. Fusulines, bryozoan, crinoid hash. Collection
7/16/57/6.
12) Limestone, gray weathering, massive beds, blocks weather rounded, (not
angular). This unit has wavy bedding surfaces and seems to represent a fore
reef accumulation of dumped debris 6" to 8" beds. 7/16/57/4. 32'.
13) Covered 8' probably same as 12.
14) Limestone, light brown weathering, cliff forms 2' to 15' beds, massive
weathering as a unit along most of this ridge. 53' to top of ridge.
