instrument shack. The UFO was seen by several people.
When the "rock hounds" checked the recording tapes in the shack they found that several of the Geiger tubes had been triggered at 10:17A.M. The registered
radiation increase was about 100 times greater than the normal background activity.
Three more times during the next two months the "mineral club's" equipment recorded abnormal radiation on occasions when the grapevine reported visual
sightings of UFO's. One of the visual sightings was substantiated by radar.
After these incidents the "mineral club" kept its instruments in operation until June 1951, but nothing more was recorded. And, curiously enough, during this
period while the radiation level remained normal, the visual sightings in the area dropped off too. The "mineral club" decided to concentrate on determining
the significance of the data they had obtained.
Accordingly, the scientist and the group made a detailed study of their mountaintop findings. They had friends working on many research projects throughout the United
States and managed to visit and confer with them while on business trips. They investigated the possibility of unusual sunspot activity, but sunspots had been normal
during the brief periods of high radiation. To clinch the elimination of sunspots as a cause, their record tapes showed no burst of radiation when sunspot activity had
The "rock hounds" checked every possible research project that might have produced some stray radiation for their instruments to pick up. They found nothing.
They checked and rechecked their instruments, but could find no factor that might have induced false readings. They let other scientists in on their findings, hoping
that these outsiders might be able to put their fingers on errors that had been overlooked.
Now, more than a year after the occurrence of the mysterious incidents that they had recorded, a year spent in analyzing their data, the "rock hounds" had no
By the best scientific tests that they had been able to apply, the visual sightings and the high radiation had taken place more or less simultaneously.
Intriguing ideas are hard to kill, and this one had more than one life, possibly because of the element of mystery which surrounds the subject of flying saucers. But
the scientific mind thrives on taking the mystery out of unexplained events, so it is not surprising that the investigation went on.
According to my friend the scientist, a few people outside the laboratory where the "rock hounds" worked were told about the activities of the "mineral
club," and they started radiation- detection groups of their own.
