Castner Glacier

Castner Glacier is a glacier in Southeast Fairbanks Census Area, Alaska that spans several miles at high elevation. Along its path, visitors encounter ice caves and exposed rock faces that shape the landscape.

The glacier has experienced steady retreat since the early 1900s, a change documented by scientists over decades. These observations help explain Alaska's climate patterns.

The glacier serves as an educational site where environmental scientists conduct research on glacial movements and ice formation processes throughout the seasons.

A short trail leads from Richardson Highway to the glacier, with parking available on the southwest side of the bridge. The access is straightforward, making it possible for visitors of various abilities to explore the area.

The site contains year-round accessible ice caves that partially collapsed in 2022, creating new entry points. These fresh openings reveal how glaciers constantly transform.
