The manufacturing process is the most prominent feature of industrial landscapes: factory buildings with machinery, chimneys, furnaces, power sources such as water wheels, dams, boilers and warehouses. Because the process requires the materials be assembled in one place and products widely distributed, transportation systems are the second most prominent feature of industrial landscapes: canals, rail lines and yards, bridges, docks, and highways. The remaining features in these landscapes, which are byproducts of the process, include pollution of water and air, destruction of vegetation, and discarded products such as slag heaps, saw dust and obsolete equipment.
