This project on the Cheshiahud Lake Union Loop is an investigation of the ephemeral qualities that make traveling along a path intriguing, and how mapping and landscape art interventions can create new or enhance existing environmental qualities. Moving through space and time along the pathways that make up the loop; observing sky, water, shadows, wildlife, city life; and creating or participating in events that happen at the edge of the lake allow visitors to become part of a dynamic performance.
