Having last visited Saw Mill Playground in the South Bronx in 2016, I returned to the site to take a closer look at its neighbor, Brook Park. Both of these parks commemorate in their names the long-buried Mill Brook.
The stream was entirely covered in the 19th century, with its most visible surface reminder being Brook Avenue. At 141st Street, the community garden known as Brook Park also remembers the stream although it does not lie directly atop the former stream bed.
