1) Gaptank below is nearly vertical and strikes approximately S45°W. Here it is
a reddish to yellowish-brown with a high % of CaCO3, mostly sandstone, some
shale and siltstone.
2) Covered 13'.
3) Limestone, reddish-brown weathering, very sandy (very fine sand, quartz)
high porosity, has specks of dark material dispersed, 1mm or less in size. 5'.
8/5/57/1.
4) Covered 7', probably much like #3.
5) Calcarenite, medium gray weathering, medium sand size. No identifiable
fossils. 2.5' (a few crinoid columns).
6) Covered 2'.
7) Limestone, brownish-gray weathering, very silty, upper 2" are intraformational
conglomerate. 1.5'.
8) Covered 4'.
PG. 6
9) Limestone, medium gray weathering, a fusuline limestone. 8/5/57/2; 3'.
10) Covered, 3'.
11) Limestone, light gray, fine grained with fusuline. 1' to 3' beds, 8', 8/5/57/3.
This unit has a vertical (weathering) fracture.
12) Covered 2'.
13) Limestone, light gray like #11, but more abundant fusulines. 8/5/57/4, 6'.
14) Limestone, light yellow-brown weathering, very sandy and silty; beds 6" to 3',
12' total.
15) Limestone, medium to dark gray, very fine grain CaCO3, a calcarudite,
upwards gets mottled brown from siliceous silts, 7'. 8/5/57/5.
PG. 7
16) Limestone, light gray, dense, vertical fracturing to weathering, a calcilitute,
19', in bed 8" to 2.5' - Collection 8/5/57/6. Lenox Hills Fm '95.
17) Calcarudite; massive, 3' blocks in it, mostly has of those lithologies #2-16
but a few Gaptank types. Top is nearly flat, has some rubble marks, a dark
brown silica rich surface, 22'.
18) Sandstone, light brown, very silt rich in laminate of 1/16" or less, variable
thickness, about 5' here.
19) Limestone, medium-dark gray, massive, has just about every thing
mentionable in it. Biohermal, 35' top of unit has fault, siliceous surface.
Collection 8/5/57/7, 1' below top.
20) Like #18, 3'.
21) Limestone, conglomeratic near base, biohermal near top, yellow or tan-gray,
top is flat with 2" band on dark brown siliceous cap; total 4'.
PG. 8
22) Limestone, brownish-gray weathering, calcarenite and fine calcarudite. 1' to
top of ridge (knoll). Collection 8/5/57/8 on top of ridge.
