Gently signed by the president which
went into effect on Wednesday night
of last week.
The Mosby we'll which was brought
in recently by the Frantz corporation
is the third producing we'll in Mon
tana. The other two are located in
the Roundup field and it lis expected
that another we'll will be brought in
in that vicinity within a very short
time. There are fully a dozen rigs
drilling at the present time in that
field with any number ready for early
action upon a favorable turn of wealth
er conditions.
So far, activity in northern Mon
tana has been confined mainly to the
Bowdoin and Poplar fields on which
there are very favorable reports. From
reports at hand from both districts,
the indications are that both fields
will see marked development COM
nencing with the early spring, sew
eral companies having arranged for
rigs to be erected at the earliest pos
sible opportunity.
The following is a partial report
covering the results of survey of
the Bowdoin field by Arthur j. Col
lier and submitted to the government
in bulletin 661:
The Bowdoin dome is included in
Twps. 20 to 35 NJ, RS 80 to SO east.
Its southern part has been mapped top
ographically by the United States ge-
illogical survey. The only reliable maps
of the northern part are based on
the township plats of the general land
office. Many of the townships have
been surveyed so recently that their
plats are not yet available Attitudes
and topography along the information
al boundary are given on the sheet
prepared by the international boundary
commission, and the geological sur
vey's Typographical map of the Cherry
ridge quadrangle, 80 miles west of the
Bewdoin dome, shows the altitude of
the headwaters of some of the streams
that flow into Milk river within the
dome.
The structure revealed by the Ju-
dith river formation in it's outcrop
around the valley of Milk river, is
that of broad, flat dome. The dips
of the sandstone are so low as not to
be detected by the unaihed eye and
are best recorded in feet to the mile.
There is no place around the dome
where dip as high as 1 degree has
been found.
On the northeast, east and south
east sides of the dome the beds dip
eastward for many miles, On the west
side there is a westerly dip for about
IS miles to the neighborhood of Cher
ry ridge. On the southwest the dip
flattens, the top of the Judith river
Sandstone being about 100 feet above
the river at Coberg, % miles from
Malta, and outcrops of the same for
nation are reported to occur at in
tervals for many miles along the rail
road. A dip to the south is indicat-
ed by the outcrops of the Lance and
Fort Union formations near the Mis-
souri, river. The only place where a
dip large enough to be measured by
a clinometer was found is in the Bear
paw shale in Sec. 36, T. 36 N, R.
SO E., 80 miles northwest of the dome.
Here an inclination of 5 degrees north
east was recorded, but though search
was made for similar dips in the reeks
northwest and southeast Of this local
ity, they could not be found. It must
be noted that dips in shale alone are
difficult to determine, and that many
shale beds show small superficial in
chnations.
Along the outcrops of the Judith
river formation there are large blocks
of sandstone which have broken away
and slid down the slopes. A notable
instance of such slumping is to be seen
near the mouth of Cottonwood creek,
where a large block lies on the east
side of Milk river and has been tilted
so that its bedding is not parallel with
that Of its original position. Fea-
lures Of this kind are very suggestive
of faults, but it is thought that no
real faults are present.
The amount of dip can be seen along
Milk river between Hinsdale and Tam
