摘要

A first-time visitor to Nashville,Tenn., (or even longtime residents) would be surprised to learn about the city's "underground history." An 1800s map posted on the wall of President Andrew Jackson's nearby home, The Hermitage, reveals that the present city landscape was once cut by ravines and streams that drained to the Cumberland River. Similar to some other large cities, as urbanization proceeded, these streams — which often became open sewers — were covered over and pipes were built to convey the flows.
