June 7 – On this day in Montana history in 1964 Montana was reeling from what at that time was called the worst natural disaster in its recorded history. Heavy rains in early June sent rivers raging to a mile wide in some areas with homes, dams, roads and railroads washed away and more than 30 people left dead. On June 7 alone 10 inches of rain fell in Browning, Glacier National Park and Augusta. President Lyndon Johnson declared nine counties in northwest and north-central Montana federal disaster areas, and damages eventually totaled more than $62 million.
