On January 28, 1969, an oil well off the coast of Santa Barbara, Calif., experienced a blowout. The result was an oil spill that at the time ranked as the largest in U.S. waters.
The disaster, which made headlines across the nation, helped create the modern environmental movement. It also led to restrictions on offshore drilling — restrictions the Trump Administration is trying to loosen.
The events that led to the spill began one morning on Platform A, a rig located about six miles from the coast and operated at the time by Union Oil.
