On November 20, 1983, an explosion of an explosives storage bunker just south of Pleasant Hill occurred. Reports were that two teenagers were hunting around the area.

The two teenagers were killed in the explosion, leaving only small pieces of shirts. The explosion was felt 45 miles away from the site. At least 25 homes within a one-mile radius of the explosion suffered damage, doors and windows were blown out, ceilings fell and houses were knocked off their foundations, police said. One house, 300 yards directly up the valley from the shack, suffered an inch-wide crack the entire width of its basement wall.
