The Sierra Club Toiyabe Chapter Records (1951 to 2021) are composed of files from Sierra Club officers and environmental activists in the Southern Nevada (formerly Las Vegas) Group of the Toiyabe Chapter. The collection documents the involvement of the Southern Nevada group in a variety of environmental concerns, such as air quality, transportation, urbanization, and nuclear issues, in which the chapter has expressed interest. The records are comprised of correspondence, memoranda, meeting minutes and agendas, newspapers, magazines, newsletters, pamphlets, press releases, legislation, recommendations, resolutions, and general information. Due to the group’s location in the heart of the Mojave Desert, the collection provides excellent case studies of significant changes in the post-World War II American environmental movement, notably the increased recognition of the worth of desert lands.
The Basic Magnesium Inc. (BMI) Records and Photographs (1933-1965) document the planning, construction, and management of the BMI magnesium manufacturing plants near present-day Henderson in Clark County, Nevada and a magnesium mining operation in Gabbs, Nye County, Nevada. Materials include chronological reports, press releases, telegrams, budgets, building diagrams, maps, and black-and-white photographic prints. The records document employee housing and infrastructure projects, magnesium production statistics, and employee data. The photographic prints, which include many aerial images, provide a visual record of the construction of the plant, the mining operation, and the associated support facilities and employee housing.
