Isabelle Glacier is an alpine glacier located .25 mi (0.40 km) southwest of Shoshoni Peak, in Roosevelt National Forest in the US state of Colorado. [2] The glacier is immediately east of the Continental Divide on the opposite side of the divide from Fair Glacier. Isabelle Glacier is the source of the South Saint Vrain Creek and can be reach by trail and is a 8.4 mi (13.5 km) round-trip hike from the trailhead. [3]

Grinnell Glacier glacier in Montana, United States

Grinnell Glacier is in the heart of Glacier National Park in the U.S. state of Montana. The glacier is named for George Bird Grinnell, an early American conservationist and explorer, who was also a strong advocate of ensuring the creation of Glacier National Park. The glacier is in the Lewis Range and rests on the north flank of Mount Gould at an altitude averaging 7,000 feet (2,100 m), in the Many Glacier region of the park.

Schoolroom Glacier glacier in the United States

Schoolroom Glacier is a small glacier in Grand Teton National Park in the U.S. state of Wyoming. This Teton Range glacier lies adjacent to the south Cascade Canyon trail at an altitude of 10,400 ft (3,200 m), approximately 12 mi (19 km) from the trailhead at Jenny Lake. The glacier has many of the classic textbook details of a glacier, namely, well defined terminal and lateral moraines, crevasses, a proglacial lake and related features which led to the naming schoolroom.

Gem Glacier glacier in Montana, United States

Gem Glacier is the smallest named glacier in Glacier National Park (U.S.). Located on the east side of the Continental Divide arête known as the Garden Wall, the glacier is situated on the cliff face above the better known Grinnell Glacier. Gem Glacier is a hanging glacier, and drapes down from the north face of the steep arete to which it is attached. Gem Glacier is only 5 acres (0.020 km2) in area and is far below the 25 acres (0.10 km2) threshold often cited as qualifying as an active glacier. Between 1966 and 2005, Gem Glacier lost 30 percent of its acreage and Grinnell Glacier lost 40 percent.

Lilliput Glacier glacier in California, United States

Lilliput Glacier is the smallest named glacier in the Sierra Nevada of California. The glacier has an area of .05 km2 (0.019 sq mi), which is approximately 12.2 acres. In terms of area this is about the size of 48 typical suburb lots that single family home are built on. This glacier lies on the shaded north-facing vertical cliff of Mount Stewart, being the southernmost named glacier in the United States.

Grasshopper Glacier is located in Shoshone National Forest, in the US state of Wyoming on the east of the Continental Divide in the Wind River Range. Grasshopper Glacier is in the Fitzpatrick Wilderness, and is part of the largest grouping of glaciers in the American Rocky Mountains. The glacier flows north, and glacial runoff supplies water to Grasshopper Creek, flowing eventually into the Wind River. The glacier shares a glacial margin with Klondike Glacier, located to the south. The glacier is named for grasshoppers that have been found entombed in the ice.

Swiftcurrent Glacier is in Glacier National Park in the U.S. state of Montana.The glacier is on the east side of the Continental Divide arête known as the Garden Wall. Swiftcurrent Glacier is one of several glaciers that are being monitored to determine stream flow alterations that occur due to glacial retreat. Compared to other glaciers in Glacier National Park, Swiftcurrent Glacier has experienced relatively slow retreat. As of 2005, the glacier had an area of 55 acres (0.22 km2), a 14 percent reduction since 1966.

The Salamander Glacier glacier in the United States

The Salamander Glacier is in Glacier National Park in the U.S. state of Montana. The glacier lies on a shelf on the east side of the arête which is part of the Continental Divide, at an average elevation of 7,200 feet (2,200 m) above sea level. The Salamander Glacier covered an area of approximately 57 acres (0.23 km2) as of 1993. Before Grinnell Glacier retreated significantly, it used to encompass The Salamander Glacier and the two become separate sometime before 1929. The Salamander Glacier was measured at 42 acres (0.17 km2) in 2005, which is a 23 percent reduction since 1966. Though only .10 mi (0.16 km) in length, The Salamander Glacier is about .75 mi (1.21 km) wide.
