Chromite Deposits Near Red Lodge and Silver Star, Montana

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.

Shaping a Bright Future for Montana Tech: Developing State, National and Global Leaders in Resource Sectors

Presentation by Leigh W. Freeman. Rachel Carson's book Silent Spring published in 1962 marked the birth of concepts leading to the development of mineral resources with a balance of economic, environmental and social imperatives. Montana plays a special role in this story. It is 'the last best place.' As such it can serve as a bell-weather state for Carson's revelations. Consider: Butte as a poster child for legacy problems resulting from resource development under solely economic imperatives; and Montana as a first-adapter in 1971 of state environmental laws based on imperatives heralded with Silent Spring. What better place is there to educate and develop leaders and incubate the future of resource development in global sustainability?

Revegetation and Bird Trends, Silver Bow Creek Superfund Remediation and Restoration

Silver Bow Creek runs approximately 25 miles from Butte to Warm Springs, where it joins Warm Springs Creek to form the Clark Fork River. This historic creek was terribly contaminated with mine wastes around the turn of the 20th century, leaving many "slickens" that persisted into the 21st century, when it became a Superfund remediation project. More than 5.5 million cubic yards of stream-deposited mine waste have been removed and 1,650 acres revegetated. Chief contaminants are copper, zinc, and arsenic, but acidic soils are often equally or more limiting to plants. The stream was relocated, and mine wastes were replaced with biologically inert cover soil. Richard A. Prodgers is currently a plant ecologist with Bighorn Environmental Sciences in Dillon, Montana.

The Effect of Boron on the Hardenability of Steel

Many attempts have been made to improve iron and steel and their alloys by the addition of boron. The re­sults obtained were not encouraging for the reason that the amount of boron used, generally from 0.2 to 2.0 per cent is altogether too high. This percentage of boron ren­ders the product hard and brittle and of late the experiments with boron in this connection have been practically abandoned.
