About The Cover

Enhanced Landsat Thematic Mapper image of the area of the Cady Mountains and Bristol Mountains in the eastern Mojave Desert, California. Color variations primarily denote contrasting iron- and hydroxyl-bearing constituents of the surficial rocks and sediments. The image enhancement reveals faults and associated structural features that were overlooked in previous field mapping. See page 1000.
