In 1987, Prophet predicted a first strike by the Soviet Union if America did not implement a missile defense program. She began to admonish her followers to move to Montana and build nuclear fallout shelters for the impending nuclear holocaust. Adherents started construction of a large bomb shelter in the church compound in Corwin Springs, Montana on land purchased from magazine publisher Malcolm Forbes. Church members not on the staff built private shelters nearby. In April 1990 at Prophet's prompting, the entire community spent the night in their various shelters, communicating with each other by radio. Insiders, however, spread the word that the event might be the real thing. No one knew for sure, and many children believed this could be the end of life as they knew it. Nothing happened, and Prophet's focus took a gradual turn away from nuclear prepping and toward community outreach. Around this same time, the nearly-completed construction was halted by court order when large amounts of stored diesel fuel leaked and contaminated the area.
