Upper Fremont Glacier, Alpine glacier in Shoshone National Forest, Wyoming, US.
Upper Fremont Glacier extends 1.35 miles in length across the northern slope of Fremont Peak at an elevation of 13,450 feet in the Wind River Range.
Scientists extracted a 538-foot ice core in 1998, revealing temperature changes and atmospheric composition data from the past several centuries in North America.
Researchers regularly conduct studies on the glacier to measure environmental changes, making it a reference point for climate science in the Rocky Mountains.
The glacier remains accessible through established hiking trails in the Fitzpatrick Wilderness, requiring proper mountaineering equipment and experience for safe exploration.
The ice cores from Upper Fremont Glacier contain records of mercury levels that document the effects of the Industrial Revolution and subsequent environmental regulations.
