America Underground

Did you ever think about what is under your feet? Beneath a dirt path are endless roots and numerous living creatures. Under city streets are water pipes, gas lines, subways. Go deeper and there are caves and caverns, coal and mineral mines, tunnels for automobiles and trains, wells for water, storage space for warehouses and offices, landfills for waste. This fascinating book looks beneath the surface and shows what is down there and how it got there. The 1.1 million miles of pipelines for natural gas outnumber those for oil. Kansas City has the most underground storage area. N.Y. City has the longest subway system. Gold is stored underground because it is too heavy for any floor. There is an amazing world beneath you!
