New evidence found in the Rocky Mountains of Colorado supports the notion that Snowball Earth was indeed a global phenomenon.

Even the balmy tropics may have once been crushed by colossal masses of ice.

New research from the University of Colorado Boulder provides evidence supporting the 'Snowball Earth' theory. Geologists found that sandstones in Colorado, dating back 690 to 660 million years ago, were likely forced underground by the pressure of massive glaciers.

The presence of glacial evidence in this location strongly supports the idea that ice covered the entire planet.

The researchers have stumbled upon evidence of "Snowball Earth" which existed between around 720 to 635 million years because of the climate
