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. [2] 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. [3] 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. [3] 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. [3]

The Wind River Range is a mountain range of the Rocky Mountains in western Wyoming in the United States. The range runs roughly NW–SE for approximately 100 mi (160 km). The Continental Divide follows the crest of the range and includes Gannett Peak, which at 13,802 ft (4,207 m), is the highest peak in Wyoming; and also Fremont Peak at 13,750 ft (4,191 m), the third highest peak in Wyoming. There are more than 40 other named peaks in excess of 12,999 ft (3,962 m). With the exception of the Grand Teton in the Teton Range, the next 19 highest peaks in Wyoming after Gannett are also in the Winds.

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 290.36 miles in any direction.

<span class="mw-page-title-main">Gannett Glacier</span>

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.

<span class="mw-page-title-main">Mount Warren</span> Mountain in the state of Wyoming

Mount Warren is located in the Wind River Range in the U.S. state of Wyoming. The peak is the third peak in the range and the fourth tallest in Wyoming. The summit is located in the Fitzpatrick Wilderness of Shoshone National Forest and rises above several glaciers, the best known being Dinwoody Glacier which is immediately north of the summit tower. The mountain abuts, but is not within, either Bridger National Forest or Sublette County, Wyoming.

Doublet Peak is the sixth-highest peak in the U.S. state of Wyoming and the fifth-highest in the Wind River Range. The summit is immediately south of Dinwoody Glacier and just west of Mount Warren.

<span class="mw-page-title-main">Sourdough Glacier</span> Glacier in the state of Wyoming

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.

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.

<span class="mw-page-title-main">Minor Glacier</span> Glacier in the state of Wyoming

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.

Gooseneck Glacier is located in the Fitzpatrick Wilderness, Shoshone National Forest, in the US state of Wyoming. The glacier is east of the Continental Divide in the northern Wind River Range and on the southeast flank of Gannett Peak, the tallest mountain in Wyoming. Gooseneck Glacier is separated from Dinwoody Glacier by a rocky outcropping and they are part of the largest grouping of glaciers in the American Rocky Mountains.
