Adams Glacier

Adams Glacier is a large expanse of ice on Mount Adams's northwestern slope, flowing downward from the summit cap and terminating at lower elevations. The surface displays characteristic crevasses and ice formations that are visible throughout the year and shape the appearance of the upper mountain.

The glacier was documented during early 20th-century surveys of Mount Adams as climbers and scientists explored the upper mountain regions. Changes to its extent over the decades reflect broader shifts occurring in high-altitude ice fields across North America.

The glacier serves as a defining landmark in the mountain landscape, helping climbers navigate through the high alpine terrain and mark their progress during ascents.

Plan for a full day of hiking with sturdy footwear suitable for steep and rocky terrain encountered on the approach. Established campsites along the route offer places to rest, making it practical to split the climb across multiple days if needed.

The glacier connects two major long-distance hiking routes, making it an important waypoint for many trekkers crossing the high country. This geographic situation means that routes through the ice can change seasonally, affecting how climbers navigate their approach.
