Context paragraphs:
Dinwoody Glacier: 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 in thickness.  Radar mapping of 72 locations on the glacier resulted in an average thickness of 54 m and a maximum measured depth of 111 m .  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.

Continental Glacier: Continental Glacier is in Bridger-Teton and Shoshone National Forests, in the U.S. state of Wyoming and straddles the Continental Divide in the northern Wind River Range.  Continental Glacier is in both the Bridger and Fitzpatrick Wildernesses, and is part of the largest grouping of glaciers in the American Rocky Mountains.  Continental Glacier is situated at an elevation range of 13100 to and forms a nearly unbroken icefield over 3 mi in length along a high altitude plateau to the north of Downs Mountain.  Immediately east of Continental Glacier lies East Torrey Glacier.

Little Belt Mountains: The Little Belt Mountains are a section of the Rocky Mountains in the U.S. state of Montana.  Situated mainly in the Lewis and Clark National Forest, the mountains are used for logging and recreation for the residents of Great Falls, Montana.  Showdown is a ski area located within the mountains located off US Highway 89 which splits the mountains in half connecting White Sulphur Springs and Belt, MT.  The highest point in the Little Belt Range is Big Baldy Mountain at 9175 ft .

Mission Mountains: The Mission Mountains or Mission Range are a range of the Rocky Mountains located in northwestern Montana in the United States.  They lie chiefly in Lake County and Missoula County and are south and east of Flathead Lake and west of the Swan Range.  On the east side of the range is the Swan

Barton Mountains: The Barton Mountains ( ) are a group of mountains located south of the Commonwealth Range and the Hughes Range and bounded by Keltie Glacier, Brandau Glacier, Leigh Hunt Glacier, and Snakeskin Glacier, in the Queen Maud Mountains.  They were mapped by the United States Geological Survey from surveys and from U.S. Navy aerial photographs, 1958–63.

Anaconda Range: The Anaconda Range, informally known as the "Pintlers", is a group of high mountains located in southwestern Montana, in the northwestern United States.  The mountain range takes its name from the nearby town of Anaconda, founded by Marcus Daly in 1883.  It runs northeast approximately 50 miles (80 km) from Lost Trail Pass to a point near the community of Anaconda, covering parts of Ravalli, Deer Lodge, Granite and Beaverhead Counties.  To the northwest are the Sapphire Mountains, to the south is the Big Hole Valley.  Due north, the range blends into the Flint Creek Range, and to the southeast lies the Big Hole River and Pioneer Mountains.  The crest of the range is part of the Continental Divide, rising to 10,793 feet (3290 m) at West Goat Peak.  Other major summits include Mt. Evans (10,641 ft, 3243 m), Mt. Haggin (10,607 ft, 3233 m), Warren Peak (10,463 ft, 3189 m), and East Goat Peak (10,399 ft, 3170 m).  West Pintler Peak, located in a more commonly visited area, rises to 9894 feet (2895 m).  Much of the range is protected in the Anaconda-Pintler Wilderness Area.

Sunrise Glacier (Montana): Sunrise Glacier is in the U.S. state of Montana.  Sunrise Glacier is situated in the Mission Mountains at an elevation of 8800 ft above sea level and is east of Mount Shoemaker.  The glacier covers approximately 35 acres .

Grasshopper Glacier (Wyoming): 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.

Glacier County, Montana: Glacier County is located in the U.S. state of Montana.  As of the 2010 census, the population was 13,399.  The county is located in northwestern Montana between the Great Plains and the Rocky Mountains, known to the Blackfeet as the "Backbone of the World".  The county is geographically and culturally diverse and includes the Blackfeet Native American Reservation, Glacier National Park, and Lewis and Clark National Forest.  The county is bordered by 75 miles of international boundary with two ports of entry (Piegan and Del Bonita) open year-round and one seasonal (Chief Mountain) international border crossing into Alberta, Canada.

Needle Mountains: The Needle Mountains are a subrange of the San Juan Mountains of the Rocky Mountains located in the southwestern part of the U.S. State of Colorado.  Much of the range is protected in the Weminuche Wilderness of the San Juan National Forest.  The range is notable for having some of the most rugged mountains in the state, and includes many technical climbs and scrambles.  A small but dramatic east-west subrange in the northern section is known as the Grenadier Range.
