Figure 9.20: Three primary industrial landscapes.(a) This bizarrely colored industrial mosaic is on the margins of the Great Salt Lake in Utah, where chemicals and minerals such as metallic magnesium, potassium, and sodium chloride are derived from the water by solar evaporation. (b) This open-pit mine is Bingham Canyon in Utah, the second largest in the world. (c) This mind-boggling artificial alp is the result of potash mining near Kassel in Germany.
