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

We have an extremely incomplete picture of what these snowball periods looked like, and Antarctic terrain provides different models for what an icehouse continent might look like. But now, researchers have found deposits that they argue were formed beneath a massive ice sheet that was being melted from below by volcanic activity.

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