Gannett Peak is the highest mountain peak in the U.S. state of Wyoming at 13,810 feet (4,210 m). It lies in the Wind River Range within the Bridger Wilderness of the Bridger-Teton National Forest. Straddling the Continental Divide along the boundary between Fremont and Sublette counties, it has the second greatest topographic prominence in the state (7076') after Cloud Peak (7077'), and is the highest ground for 290 miles in any direction.
Fremont Peak is the third highest peak in the state of Wyoming, surpassed only by Gannett Peak and Grand Teton, and straddles the boundary between Fremont and Sublette counties in the Wind River Range. It is named for American explorer John C. Fremont who climbed the peak with Charles Preuss and Johnny Janisse from August 13 to August 15, 1842. Kit Carson had been with the climbing party on its first attempt at the peak, but had gone back for supplies the day Fremont and his men reached the summit. Carson is thought by some to have been the first to climb neighboring Jackson Peak. At that time, Fremont Peak was mistakenly thought to be the highest mountain in the Rocky Mountains, although there are actually over 100 higher peaks in the Rocky Mountain range.
Gannett Glacier is the largest glacier in the Rocky Mountains within the United States. The glacier is located on the east and north slopes of Gannett Peak, the highest mountain in Wyoming, on the east side of the Continental Divide in the Wind River Range. Gannett is but one of dozens of glaciers located in the Fitzpatrick Wilderness of Shoshone National Forest.
Dinwoody Glacier is located in Shoshone National Forest, in the U.S. state of Wyoming on the east side of the Continental Divide in the Wind River Range. Completely within the Fitzpatrick Wilderness, Dinwoody Glacier is one of the largest glaciers in the American Rocky Mountains, and as of 1989 was ranked fourth in area. In a 1989 study which examined repeat photography and stream flow analysis, Dinwoody Glacier was determined to have retreated rapidly between 1958 and 1983, though most of the reduction has been in the thickness of the glacier rather than its surface area. In the same 25-year period, the glacier lost an average of 23.4 m (77 ft) in thickness. Radar mapping of 72 locations on the glacier resulted in an average thickness of 54 m (177 ft) and a maximum measured depth of 111 m (364 ft). The 1989 study was commenced to examine the impact on water supplies to streams and rivers from glacier retreat of both Dinwoody and Gannett Glaciers.
Sourdough Glacier is in the Wind River Range, Bridger-Teton National Forest in the U.S. state of Wyoming. Sourdough Glacier is in the Bridger Wilderness, and is part of the largest grouping of glaciers in the American Rocky Mountains. The glacier extends from the north slope of Klondike Peak at an elevation range of 12,800 to 11,800 ft and flows into a proglacial lake.
J Glacier is located in Bridger-Teton National Forest, in the US state of Wyoming on the west of the Continental Divide in the Wind River Range. J Glacier is in the Bridger Wilderness, and is part of the largest grouping of glaciers in the American Rocky Mountains.

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.
Minor Glacier is in Bridger-Teton National Forest, in the U.S. state of Wyoming on the west side of the Continental Divide in the northern Wind River Range. Minor Glacier is in the Bridger Wilderness and is part of the largest grouping of glaciers in the American Rocky Mountains. The glacier is situated below the west flank of Gannett Peak, the tallest mountain in Wyoming.
Mammoth Glacier is in the Bridger Wilderness of Bridger-Teton National Forest, in the U.S. state of Wyoming. The glacier is on the west side of the Continental Divide which separates it from Dinwoody Glacier to the east. Mammoth Glacier is the largest glacier on the west side of the Continental Divide of the Wind River Range and occupies a large, north facing cirque on the north slopes of Twin Peaks and just west of Mount Woodrow Wilson. Mammoth Glacier is part of the largest grouping of glaciers in the American Rocky Mountains.
Baby Glacier is in the Bridger Wilderness of Bridger-Teton National Forest, in the U.S. state of Wyoming. The glacier is immediately west of the much larger Mammoth Glacier, both of which are on the west side of the Continental Divide in the northern Wind River Range. The glacier occupies a north facing cirque and flows northward from the slopes of Mount Whitecap. Baby Glacier is in the Bridger Wilderness and is part of the largest grouping of glaciers in the American Rocky Mountains.
Stroud Glacier is west of the Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is located in the Bridger Wilderness of Bridger-Teton National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. The glacier is situated in a north facing cirque, below the summit of Bow Mountain.
Twins Glacier is west of the Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is located in the Bridger Wilderness of Bridger-Teton National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. The glacier is situated in a northeast facing cirque, below the summit of Winifred Peak.
Heap Steep Glacier is located east of the Continental Divide in the northern Wind River Range in the US state of Wyoming. The glacier is situated in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. Heap Steep Glacier is in a north facing cirque, below the summit of Sunbeam Peak. A large terminal moraine and small proglacial lake are located below the glacier.
Helen Glacier is located east of the Continental Divide in the northern Wind River Range in the US state of Wyoming. The glacier is located in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. Helen Glacier flows to the east from a cirque to the northeast of Mount Helen.
Lower Fremont Glacier is east of the Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. Lower Fremont Glacier flows to the southeast and the rapid retreat of this glacier has left behind lateral moraines and a proglacial lake. Lower Fremont Glacier is separated from the Bull Lake Glacier by a moraine and from the Upper Fremont Glacier by cliffs.
Bull Lake Glacier is located immediately east of the Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. Bull Lake Glacier flows to the east and starts below the summit of Jackson Peak. It is adjacent to Lower Fremont Glacier though the two are separated by a moraine.
Knife Point Glacier is on the east side Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains.

Harrower Glacier is located on the west side of the Continental Divide in the northern Wind River Range in the US state of Wyoming. The glacier is in the Bridger Wilderness of Bridger-Teton National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains.
