A park ranger leads visitors to ancient fossil formations known as stromatolites during a guided nature tour of Glacier National Park, a vast wilderness preserve in northwestern Montana, USA. These round rock-like structures were formed in shallow waters as long ago as 3 billion years when living microorganisms called cyanobacteria trapped layers of sediment. Geological features like stromatolites are among the many natural attractions for visitors to this pristine scenic region that was established as America's 10th national park in 1910.

Geological features like stromatolites are among the many natural attractions for visitors to this pristine scenic region that was established as America's 10th national park in 1910. Unfortunately the numerous glaciers for which the park is named have suffered from climate change over the years. From an estimated 146 glaciers in the mid-19th century, only 26 named glaciers remained the park as of 2020.
