Rocks on Colorado's Pikes Peak reveal clues about Earth's ancient "Snowball Earth" phase.

Unusual rocks found on Colorado's Pikes Peak offer clues about Earth's "Snowball Earth" phase, when the planet was entirely covered in ice over 700 million years ago. Researchers used radiometric dating to determine that these pebbly sandstones, formed under immense ice pressure, are from the Snowball Earth period. This discovery provides insight into the geological processes and conditions during this icy era, contributing to our understanding of Earth's history and the evolution of early life.
