ttan, creeks and streams once flowed freely. The remnants of these once-pristine waterways are all over the Big Apple, hidden in plain sight. Hidden Waters of New York City offers a glimpse at the big city's forgotten past and ever-changing present, including:

• Minetta Brook, which ran through today's Greenwich Village
• Collect Pond in the Financial District, the city's first water source
• Newtown Creek, separating Brooklyn and Queens
• Bronx River, still a hotspot for urban canoeing and hiking

Filled with eye-opening historical anecdotes and walking tours of all five boroughs, this is a side of New York City you've never seen.
