Nuclear Blasts in Mississippi
At 10:00 a.m. on October 22, 1964, the United States government detonated an underground nuclear device in Lamar County, in south Mississippi. Residents there felt three separate shocks, and watched as the soil rose and behaved like ocean waves. Hunting dogs howled in terror, and two miles from the test site the blast shook pecans off the pecan trees. This nuclear test, and the one that followed two years later at the same Mississippi site, were the only nuclear explosions on U.S. soil east of the Rocky Mountain states.
