Covered below
1) Calcarenite, pebbles 1.5" to 2" max, Calcarenite sand matrix and Calcareous
cement. Fossiliferous (Crinoids and fusulines), bedding 1' to 1.5'. Flat top 4.5'
gray fresh, light yellow-brown weathering.
2) Covered 5.5' probably shale or weakly cemented rubble.
3) Calcarenite, with a few small pebble, fusulines bryozoans and crinoids
common. Quartz sands in upper part, 18", flat top. Yellowish-brown weathering.
4) Covered 17', probably shale and 1 or 2 calcarenite beds (less than 4-6" thick).
5) Calcarenite, brown weathering, some quartz sand 8" thick.

{note: illustration:
bed 1: 7/657/1
bed 9: 7/6/57/2; 7/6/57/3, loose}
6) Calcarenite, gray-brown weathering, shell hash, fusulines, crinoids and
brachs. Lower part of unit is a shale which grades into a limestone rubble, then
into a well sorted frag. limestone. Upper surface is planed flat. Total 5'.
7) Covered 8' - gray shale and some silty calcarenite.
8) Calcarenite - well graded medium sand, a few fusulines (small) and stem
joints of crinoids - several beds in a 4' interval.
9) Covered 76'. The lower 20 feet is probably mostly blue-gray shale. The
upper 15' probably mostly limestone rubble.

10) Calcarenite, 2" diameter pebbles, some crinoids and bryozoans a few
fusulines, brown weathering , gray on fresh surface 4'.
11)
a) shale break - 1'.
b) 4-6" well sorted Calcarenite, laminated upper 2", flat upper surface.
Total 1.5'.
12) Covered 24' - probably shale (gray) - 1 or more brown calcarenites maybe
present.
13) Calcarenite, brown weathering, lower part a shell hash, a shale break and
then the well sorted 4-8" calcarenite laminated bed. Total for unit 4.5'.
14) Calcarenite, (limestone rubble) [The main difference between the "so called"
rubble and what I've been calling limestone conglomerate or calcarenite seems
to be the cementing material. In the "rubbles" the cement is clay and it weathers
to a yellow or yellow-brown] gray and mottled brown weathering. 18' in 6-18"
beds.
