The
Dugway sheep incident, also known as the
Skull Valley sheep kill, was a 1968 sheep kill that has been connected to
United States Army chemical and biological warfare programs at
Dugway Proving Ground in
Utah. Six thousand
sheep were killed on ranches near the base, and the popular explanation blamed Army testing of
chemical weapons for the incident, though alternative explanations have been offered. A report, commissioned by Air Force Press Officer Jesse Stay and first made public in 1998, was called the "first documented admission" from the Army that a
nerve agent killed the sheep at
Skull Valley.
