Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel
Chromite Deposits Near Red Lodge And Silver Star, Montana, Edmond F. Smigel
Bachelors Theses and Reports, 1928 - 1970
The Red Lodge and Silver Star chromite deposits of Montana have stimulated much interest during periods of war. The Red Lodge deposit is 25 miles southwest of Red Lodge which is also the nearest railroad point. Several workings are scattered throughout the area, exposing lense-like ore bodies averaging 33% chrome oxide. Silver Star is a much smaller deposit 5 miles west of Silver Star, Montana, which is its nearest railroad point. Lenses of chromite are exposed by pits and trenches, which average approximately 36% chromic oxide.

It is known that there are large deposits of chromium ore in Stillwater and Carbon Counties in South-Central Montana. The late James F. Kemp of Columbia University, stated in 1928, that these were the largest chromium deposits in the United States and probably in the world, although they were not considered of commercial grade as compared with foreign ores.

Geologic Field Mapping In An Area Eight Miles North Of Three Forks, Montana, H. E. Lillis
Bachelors Theses and Reports, 1928 - 1970
The Three Forks are includes parts of Jefferson, Madison, Broadwater Pond Gallatin counties, Montana. Sedimentary formations lie at the surface nearly everywhere in the area, and the rugged surface topography has been developed through the folding and tilting of these formations and their differential erosion.
