Jun 29, 2006 — This summer marks the 30th anniversary of the "Slick of '76", a 300,000 gallon oil spill in the heart of the Thousand Islands. Thick, gooey crude coated the shoreline from Alexandria Bay to Massena. The accident remains one of the largest inland oil spills in the United States. Many river residents still remember where they were on June 23, 1976. The event re-shaped the way a generation views its relationship to the river and the giant freighters that ply its waters.
