Section 37 - 1/2 mile NE of Hess Ranch House - level shots - dip 10°.
1) Igneous intrusion, it is really a syenite dike.
2) Covered, 5'.
3) Calcarudite, 8" to 12" boulders, quartzite and chert pebbles up to 1" diameter,
orange-brown sand matrix 4' beds; 25'.
4) Covered, 35', probably conglomerate like #3.
5) Calcarudite; pebbles and cobbles of limestone, well rounded, light yellow
sand matrix. Some chert and quartzite (up to 25%). 8/23/57/1 at base; 8/23/57/2
40' up. Total - 49'.
6) Limestone, calcarenite, some limestone pebbles, but most pebbles are 1/2"
chert. This is gradational with 5 below in the last 15' of that (#5) unit. This unit
(#6) becomes progressively less conglomeratic upwards, 1'-3' beds. 8/23/57/3;
11' above base.
8/23/57/4; 32' above base. Total - 32'.

7) Calcarenite, brown-gray weathering, 2" to 3' beds, little chert pebbles. 22'.
8/23/57/5 near top.
8) Covered, 7'.
9) Dolostone; dark to medium gray, slightly brownish, 1'-4' beds, replaced fossils
but they lack internal structures. 115'. [continued page 104] {note: illustration
followed}

Section 38; N25W up slope behind Hess Ranch, level bunton traverse. [dip
about 15°N].
covered below
1) Calcarudite, with yellowish-brown sand matrix, some pebbles of chert 1"
diameter; most limestone cobbles 4"-6" diameter. 65'.
2) Calcarenite, medium gray, coarse sand size, 4" to 8" beds; 8/23/57/6 at base.
Many beds of fusulinid limestone. 8/23/57/7 at 16'. Total 38'.
3) Conglomerate, chert pebbles 1/2" diameter average 3'; probably a lense in #2
lithology. 8/23/57/8.
4) Like #2, 16'. 8/23/57/9 near top.
5) Dolostone, 14'; top or ridge - dark gray, 1'-2' beds, {note: illustration followed}.

8/24/57/1 - South side Leonard Mt., 100'-150' below massive calcaredite in a
probable terva block. The beds are dipping to east about 12°-15°. - [Gaptank in
place] see 7/23/58/2.
