creek, both emptying into the Mis-
souri, river, north of the area mop
ped. These creeks have deep cut
coulees showing exposures practi-
cally the entire length. The topo-
graphical high points of the Wayne
structure Sullivan anticline) are
fairly consistent with the structural
high points.
StratIgraphy
"The exposures along the surface
of the axis of the structure are L
the upper part of the Kootenai form
alton, in fact, the surface of the en-
tire area is Kootenai until you go
south to the edge of Belt creek,
where you find exposures Of the Nor
rison, Ellis, and Quadrant, down to
the Madison limestone. In drilling
on this structure the formations will
in all probability, be the Kootenai,
the Morrison, the Ellis, and the Qua
drant. There are exposures showing
sands in all these formations. In
the Ellis and Quadrant formations
there are sands with a thickness of
40 feet. Practically all of these
sands in the aforementioned forma-
tions are known to have produced oil
in different sections of the Rocky
mountain region, and in fact the
two predominant producing sands
of the Sunburst field are n in the
Kootenai and one at the bottom of
the Ellis. The Kootenai is the prin-
cipal producing horizon of Cat Creek.
Also from all the evidence possible
to obtain it is the horizon in which
light oil was found in the Belts well,
a few miles south of Stockett and
10 miles west of this structure; in
this horizon, a good showing of oil
was found in the two wells drilled at
Vaughn, indicating that production
is possible from sands in this forma-
ton, in this particular district.
Structure
eIn the section examined the
structure possesses features of fair
" sharp anticIines, with dips from
two to 10 degrees, and sharp syn
clines of varied depths, with the
long normal north dip averaging
two to three degrees, continu-
ing for many miles to the north.

emulation of oil and gas. With
good drainage, and a known hydro
static pressure as revealed in the two
wells drilled at Vaughn, 80 miles
vest and north and in the well drill
ed at Benton lake, 81 miles north
west, and the well drilled at the con-
fluence of the Sun and Missouri riv
ers, at a distance of about Is miles

ture, indicating that accumulation
If oil and gas should be found close
o the highs in this structure. On
he east there is a pronounced syn
cline some distance east of Belt
Butte and running in the shape of a
crescent, in a northwesterly direc-
ion to Sheppard's Butte, a distance
If about 10 miles. On the west
is a synclipal condition run
ling northwesterly and a little to
he west of Box Elder creek, for a
distance of 10 to Is miles. On the
outh there is a radial fault running
rom near Eden, in township 10, a.
asst, to a point south of Arlington,
n township Is, Feast, and two other
mailer faults running from east of
'elt, in township 10, least, west to
he district of Stockett, in township
9, 5-east, which faults are shown
ute plainly in some of the coal
mines of the Belt district. These
aults, in the opinion Of the writer,
nth the addition of the east and
rest, small but sharp synclines, pos
lively closes this structure on the
outh side. This faulted condition, L
