Updated route map and detail map of recently added
Lucerne Subdivision and
Cemex's Black Mountain spur.
A tiny bit of information taken shamelessly from the web;
Omya California Inc.Omya's plant in Lucerne Valley, California is a dry grinding facility providing bright white calcium carbonate products ranging in size from the coarsest products with a median diameter of 45 microns down to the finest product with a median diameter of 2 microns. The Lucerne Valley facility utilizes very pure stone that has excellent color. The products are shipped in bulk, semi-bulk bags and 50# bags to paint, plastics and building products customers throughout the southwestern United States.

Cemex Cement Apple Valley Black MountainToday, the CEMEX’s Black Mountain plant is the largest Portland cement facility in the United States . The High Desert mining industry boomed after World War II. Many returning GIs moved to California creating a need for additional infrastructure. These new families needed homes, schools, roads, etc. This building boom needed limestone for the required construction materials; cement for concrete, fine grind limestone for glass, roofing products, paints, adhesives and stucco. Limestone is also important as a filler in plastics and paper and is important in pharmaceutical products such as toothpaste and medicines. People like Henry J. Kaiser were instrumental in building the current mining industry in the High Desert . [/i]
As a reminder, these newly added areas along with the Mojave Subdivision will be unscenicked for the beta release. (Apart from the odd area here and there that I had an urge to do)
