It’s easy to miss the fact that our cities often cover up existing streams and rivers, often diverting them underground or into existing storm drain systems. Back in 2009, Spacing posted a wonderful map of Montréal’s hidden rivers.
Ghost rivers is a street-level art project tracking a submerged river in Baltimore:
Ghost Rivers is a new 1.5-mile-long public art installation and walking tour by artist Bruce Willen that visualizes a lost stream buried below the streets of Baltimore.
This project explores the hidden history and path of Sumwalt Run, which now flows through underground culverts beneath the Remington and Charles Village neighborhoods.
