4) shale, light brown, vitreous, and calcareous,
6" with numerous juruline (Coll. 9/3/58/1
near base;) — 16'
5) Covered, probably like 4 — 35'
(a few scattered float samples suggest
same jurulined types)
6) Conglomerate, many chert & co. pebbles < 3" diam,
brown sandstone matrix with jurulinoids (S.I. means) — 8'
7) Covered, probably shale, & as interbedded 100' ±
coll 9/3/58/2 = float
8) Ls., in large part organic peay, maybe [25]
9) part has cobbles in it. — ~~10~~
10) Covered, Ls+shale probably 40'
[10] Dolostone, brown weathered — 40 —
overlain by Leonard Shales.

This interval 6-9 apparently thins to
the E along the face of Leonard Mt.
The massive conglomerate there is represented
in section 44 by 8' (bed 6) but the
shales are largely a lateral equivalent
of that congo. Shells in the eastern
point of Leonard Mt. just above the congo
are both in large part cross-lidded
and then thinned W to sect 44, thus
beds 7+8 are its lateral equivalent.
The massive dolostone thins toward sect 44
by layers of cherty lidded Ls on its
upper surface. Just west of sect 44,
the dolostone is nearly completely missing.
The northern slope, the hill west of
Iron Mt., like most of the rest of the
hill is covered by talus blocks. The
first beds exposed below the LS sequence
are folded Gay tanks containing very small
triticles. There is apparently a trough
or syncline of Niobraran age rocks
in the triangle between SE Leonard Mt,
nw Iron Mt., and again due west of the
southern tip of Smeall.
