On September 6, 1967, Standard Oil of California's 18,000-ton tanker SS "R.C. Stoner" was driven onto the reef at Wake Island by a strong southwesterly wind after the ship failed to moor to the two buoys near the harbor entrance. An estimated six million gallons of refined fuel oil – including 5.7 million gallons of aviation fuel, 168,000 gallons of diesel oil and 138,600 gallons of bunker C fuel – spilled into the small boat harbor and along the southwestern coast of Wake Island to Peacock Point. Large numbers of fish were killed by the oil spill, and personnel from the FAA and crewmen from the ship cleared the area closest to the spill of dead fish.
