(3) (A) 6.6 fairly To top persistent cone unit reddish worth,
locally fossilif, some scrt cones between.
cones vary in size up to 3't in bedding
clown. Matrix is clayey sand.
(4) (B) 20.5 Clayey sand, fq v.fq, graywackys, some
highly glaucounitic louses + layers,

is layers scattered rb worth cones.
Becomes clayey th upper 3b4#; whole is

C 5.8 Clayey sand, at top discontinuous
layer cone-in-cone cones marking
local bentonitic salty clay which
seems to have become locally thoroughly
mixed thru, "worm-working" + thus
dissipated. (Note glauc & brn, A+B ended #)
(6) (D) 6.0 As below becoming somewhat more
clayey upward. At top persisted layer
cones that are apparently brown,
weather rusty brn.
(7) (E) 21.4 Lower 5't a clayey sand becoming less sandy
upward, upper 15.0 predominantly a silty
clay-clayey silt with sandy streaks + patches,
some sandy layers appear as cross-beds.
Fossils begin loose in clayey silt or in scrt.
