Notes: This work consists of 37 cast-iron sculptural panels that are set in pairs at the posts of the fence where people gather to take the Statue of Liberty ferry (3-jpg).

Notes from a excellent guided tour of the work, with text by Tony Hiss, from the Battery Conservancy site:

"River that Flows Two Ways" responds to a singular opportunity to make visible how the flow of the Hudson River, the flow of History, and the flow of people intersect at the Battery, making possible New York's ascent as one of the world's great cities...[It] is divided by bands of bronze [2-jpg] representing the river — above the water line is the human history of the Battery and below is the ecological story of the Hudson River from the glacial era to today.
