Chatter, 2020, PLA, Aluminum, 42L x 24W x 4H inches

Fourteen individual 3d prints create a shape outlining the Hudson Estuary. On the surface is chatter marks and striations that resemble marks found on rocky surfaces across the Hudson Valley that provide evidence of a Hudson Valley glacier. The gaps between pieces run north/south and east/west while the direction of the marks (when installed in the ground) run approximately 30 degrees west of south, the direction of movement of the Laurentide ice sheet as it sculpted the valley 20,000 years ago.
