Scientists recently came across dozens of dead whitebark pine trees on Wyoming's Beartooth Plateau that had been preserved beneath an ice patch for thousands of years. Radiocarbon dating revealed that the pines were around 5,

Researchers discovered more than 30 dead whitebark pine trees that were entombed in ice for millennia, representing a bygone ecosystem that could teach us about climate change

Trees dating back almost 6000 years have come to scientists' attention due to ice melting in the Rocky mountains, offering a "time capsule" into the past

An ancient fossilized forest in Montana is reemerging 600 feet higher than the present-day tree line after spending the last 5,500 years encased in alpine tundra. But as temperatures continue to warm, researchers say the ecological evidence hints at what may eventually return to the region.

Analysis of 6,000-year-old trees that melted out of a Beartooth Mountain ice patch provide a greater understanding of how current climate change could affect the Greater Yellowstone Ecosystem.
