Some Montana Coal Felds. — Roii'e. $~j 
latin field ; this field is between the Madison and Gallatin rivers, 
and but very little development has been done. It is a long 
distance, from a railroad, but has some fairly thick coal beds. 
The coal is bituminous coking coal and future developments 
will doubtless prove this to be a very profitable field. The 
formation is Laramie. 
Another field, partly in Gallatin county, is the Trail Creek 
field. This field has some good beds and was recently con- 
nected with the Northern Pacific Ry. by a spur from Chestnut. 
The third field in this county is the Yellowstone field. This 
occupies the north and eastern part of the county and is the 
most productive and largest of all the Gallatin county fields. 
The mines are mostly owned by the Northern Pacific railway 
company, and the coal from these mines is largely used in their 
locomotive engines. The coal is a good coking coal and for 
the most part belongs to the Laramie formation. 
Park County. 
This county, located in the southern part of the state, bord- 
ering on the Yellowstone, is also one of the foremost counties 
in the production of coal. It has parts of two coal fields with- 
in its boundaries and borders on the third. The most produc- 
tive beds are found in the Shields River district of the Yellow- 
stone field and in and around Cokedale, and the southern. Cin- 
nebar field, on the west bank of the Yellowstone river near the 
town of Horr. The coal from the Cinnabar field is in several 
beds. Some of these beds have been greatly altered by near-by 
volcanic action, and furnish semi-anthracite coal. The other 
beds contain a good grade of bituminous coking coal, and there 
are between three and four hundred large coking ovens at Horr. 
a small mining town situated on the Northern Pacific Park 
line, only a few miles from Gardiner, the terminus of the Park 
line and the entrance to the Yellowstone National Park. 
Sweet Crass County. 
There are parts of two fields in this county. The northern 
part is crossed by Clarks Fork field, and where coal is found 
it is of the plains kind, being removed from the mountain 
movement. The original strata have been but little, if any, 
changed and the coal found would naturally belong to the 
semi-bituminous or lignite variety. The formation is Creta- 
ceous, and the fuel found is for the most part lignite.
