Andrews Glacier glacier in Colorado, United States

Andrews Glacier is an alpine glacier in a cirque below Otis Peak in Rocky Mountain National Park in the U.S. state of Colorado. The glacier extends from Andrews Pass at nearly 12,000 to 11,700 feet with some perennial snow extending to Andrews Tarn, a small proglacial lake. When images of the glacier taken in the early 1900s are compared with those of the early 2000s, Andrews Glacier is showing a negative glacier mass balance which indicates the glacier is retreating.

It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Captain Rayburn A. Hudman, United States Marine Corps, who died in the crash of a Lockheed P2V-2n Neptune, modified for extreme range, flying in sub zero temperatures and Ski equippedfor landing on the Ice runways at McMurdo Sound Antarctica on October 18, 1956.

Marze Peak is a rock peak with twin summits near the south end of the ridge between Wessbecher Glacier and Hudman Glacier, in the Petvar Heights at the south end of the Sentinel Range, Ellsworth Mountains, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos from 1957–59, and was named by the Advisory Committee on Antarctic Names for Marion O. Marze, an aviation machinist's mate from the U.S. Navy who perished in the crash of a P2V Neptune airplane at McMurdo Sound on October 18, 1956.

Chocolate Glacier glacier in the United States

Chocolate Glacier is located on east slopes of Glacier Peak in the U.S. state of Washington. The glacier descends from 10,400 ft (3,200 m) to 5,900 ft (1,800 m) and is partially connected to Cool Glacier which lies to its south just below the summit of Glacier Peak. As is true with all the glaciers found on Glacier Peak, Chocolate Glacier is retreating. Chocolate Glacier retreated approximately 1,380 m (4,530 ft) between 1906 and 1946, however during a cooler and wetter period from about 1950 to 1979, the glacier advanced 450 m (1,480 ft). Chocolate Glacier has resumed retreating since and has given back 350 m (1,150 ft), nearing its previously recorded minimal length. The current terminus at 1800 m is still the lowest of the east side glacier. Chocolate Glacier remains heavily crevassed and active to 1900 m. The lowest 300 m of the glacier are stagnant.

North Guardian Glacier glacier in the United States

North Guardian Glacier is located on east slopes of Glacier Peak in the U.S. state of Washington. The glacier descends from 8,600 ft (2,600 m) to 6,430 ft (1,960 m) and is partially connected to Chocolate Glacier which lies to its south. As is true with all the glaciers found on Glacier Peak, North Guardian Glacier is retreating. North Guardian Glacier retreated approximately 1,500 m (4,900 ft) between 1850 and 1946, however during a cooler and wetter period from about 1950 to 1979, the glacier advanced modestly. Since then North Guardian Glacier resumed retreating and thinning and by 2005 the glacier had returned to its minimum length as recorded in 1946.

Dusty Glacier glacier in the United States

Dusty Glacier is located on northeast slopes of Glacier Peak in the U.S. state of Washington. The glacier descends from 9,022 ft (2,750 m) to 6,430 ft (1,960 m) and in places along its length is connected to North Guardian Glacier which lies to its south and Ermine Glacier to the north. As is true with all the glaciers found on Glacier Peak, Dusty Glacier is retreating. During the Little Ice Age, Dusty Glacier extended down to an altitude of 4,800 ft (1,500 m), but since approximately the year 1850, the glacier has been in a general state of retreat and has lost more than 1,500 m (4,900 ft) of its length. Dusty Glacier is heavily crevassed and the glacier ends in an ice fall at its terminus.
