The spectacular Mojave Desert landscapes within Red Rock Canyon National Conservation area draw millions of visitors each year. 

For most of the 1900s, sections of the Cotoni-Coast Dairies unit of the California Coast National Monument were mined for limestone and shale. Minerals were transported to the cement plant from the top of quarries through conveyer belts like this one.
