What Remains captures the dramatically altered landscape created by the sand and gravel operations prevalent in Port Jefferson Harbor in the 1920's and 30's. At the time this activity was very controversial with some individuals heralding it as an economic boon while others attacked it as an environmental disaster. Now the man-made cove offers a safe haven for boats and the park offers a quiet refuge for hikers wishing to find a quiet beach and a view of Long Island Sound. Nevertheless, the remains of the abandoned foundation of the processing plant, the docks, and dredging structures are sobering reminders of how man greatly altered this natural environment.
