Question: What mountainous region contains a range of mountains which features Mount Henry which shares the same state as Harrison Glacier?

full_context: Document 1: Montana: The northern section of the Divide, where the mountains give way rapidly to prairie, is part of the Rocky Mountain Front. The front is most pronounced in the Lewis Range, located primarily in Glacier National Park. Due to the configuration of mountain ranges in Glacier National Park, the Northern Divide (which begins in Alaska's Seward Peninsula) crosses this region and turns east in Montana at Triple Divide Peak. It causes the Waterton River, Belly, and Saint Mary rivers to flow north into Alberta, Canada. There they join the Saskatchewan River, which ultimately empties into Hudson Bay.
Document 2: Geography of the United States: The Great Plains come to an abrupt end at the Rocky Mountains. The Rocky Mountains form a large portion of the Western U.S., entering from Canada and stretching nearly to Mexico. The Rocky Mountain region is the highest region of the United States by average elevation. The Rocky Mountains generally contain fairly mild slopes and wider peaks compared to some of the other great mountain ranges, with a few exceptions (such as the Teton Mountains in Wyoming and the Sawatch Range in Colorado). The highest peaks of the Rockies are found in Colorado, the tallest peak being Mount Elbert at 14,440 ft (4,400 m). The Rocky Mountains contain some of the most spectacular, and well known scenery in the world. In addition, instead of being one generally continuous and solid mountain range, it is broken up into a number of smaller, intermittent mountain ranges, forming a large series of basins and valleys.
Document 3: Montana: East of the divide, several roughly parallel ranges cover the southern part of the state, including the Gravelly Range, the Madison Range, Gallatin Range, Absaroka Mountains and the Beartooth Mountains. The Beartooth Plateau is the largest continuous land mass over 10,000 feet (3,000 m) high in the continental United States. It contains the highest point in the state, Granite Peak, 12,799 feet (3,901 m) high. North of these ranges are the Big Belt Mountains, Bridger Mountains, Tobacco Roots, and several island ranges, including the Crazy Mountains and Little Belt Mountains.
Document 4: Lewis Range: The Lewis Range is a mountain range located in the Rocky Mountains of northern Montana, United States and extreme southern Alberta, Canada. It was formed as a result of the Lewis Overthrust, a geologic thrust fault resulted in the overlying of younger Cretaceous rocks by older Proterozoic rocks. The range is located within Waterton Lakes National Park in Alberta, Canada and Glacier National Park and the Bob Marshall Wilderness Complex in Montana, United States. The highest peak is Mount Cleveland at .
Document 5: Mount Henry (Montana): Mount Henry () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Mount Henry is just south of Appistoki Peak in the Two Medicine region of the park.
Document 6: Iceberg Peak (Montana): Iceberg Peak () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Iceberg Peak rises more than above Iceberg Lake and is considered a difficult climb due to the steepness and exposure climbers must endure. The peak sits astride the continental divide WNW of Mount Wilbur.
Document 7: Grasshopper Glacier (Montana): Grasshopper Glacier is in the Beartooth Mountains, Custer National Forest, Montana, U.S. The glacier is within the Absaroka-Beartooth Wilderness, a part of the Greater Yellowstone Ecosystem. Grasshopper Glacier is approximately long and wide. Starting at a point more than above sea level, the glacier originally was more than long but has receded significantly since first researched in the early 20th century. As of 2007, the glacier consists of several smaller glaciers, each occupying a different north-facing cirque. Grasshopper Glacier was named for the tens of millions of grasshoppers (locusts) that have been found entombed in the ice, some for hundreds and perhaps thousands of years. Many of the grasshoppers are of species that are now extinct, and their high level of preservation allowed early researchers to send some specimens to entomologists for identification. During this research it was discovered that some of the grasshoppers were of the extinct species "Melanoplus spretus" (Rocky Mountain locust), known to have existed at least up to the beginning of the 20th century.
Document 8: Pyramid Peak (Montana): Pyramid Peak () is in the Lewis Range, Glacier National Park in the U.S. state of Montana. Mokowanis Lake lies just northeast of the peak, and Atsina Lake is to the west.
Document 9: Mount Jackson (Montana): Mount Jackson (10,052 feet (3,064 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Mount Jackson is the fourth tallest mountain in Glacier National Park and it is situated on the Continental Divide. Both the mountain and its namesake Jackson Glacier are easily seen from the Going - to - the - Sun Road. On the southern flanks of Mount Jackson is Harrison Glacier, the largest remaining glacier in the park. Route Descriptions can be found on Summitpost or in ``A Climbers Guide to Glacier National Park.
Document 10: Mount Phillips (Montana): Mount Phillips () is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Lupfer Glacier is located on the east slope of Mount Phillips.
Document 11: Montana: The topography of the state is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montana's 100 or more named mountain ranges are concentrated in the western half of the state, most of which is geologically and geographically part of the Northern Rocky Mountains. The Absaroka and Beartooth ranges in the south-central part of the state are technically part of the Central Rocky Mountains. The Rocky Mountain Front is a significant feature in the north-central portion of the state, and there are a number of isolated island ranges that interrupt the prairie landscape common in the central and eastern parts of the state. About 60 percent of the state is prairie, part of the northern Great Plains.
Document 12: Skillet Glacier: Skillet Glacier is in Grand Teton National Park, Wyoming, United States. The glacier is situated on the eastern cliffs of Mount Moran and is easily seen from Jackson Hole. The shape of the glacier led to the naming as the uppermost section of the glacier is long and narrow and then broadens abruptly more than halfway down the mountain into a larger area, giving it the shape of a skillet or frying pan. The glacier is one of twelve that remain in Grand Teton National Park and one of five glaciers located on Mount Moran. Mountain climbers consider the Skillet Glacier route to be the fastest and one of the easiest ways to climb Mount Moran, and was the route taken when the peak was first climbed in 1922, though it is rarely used in late summer due to poor footing. On November 21, 1950, A DC-3 crashed into Mount Moran, adjacent to Skillet Glacier, killing all 21 passengers aboard. The remains of the passengers and the plane are still on the mountain.
Document 13: Harrison Glacier: Harrison Glacier is located in the US state of Montana in Glacier National Park. Situated on a southeast facing ridge immediately south of Mount Jackson, Harrison Glacier is the largest glacier in Glacier National Park and was estimated in 2005 to have an area of . Though many experts have stated that all the glaciers in Glacier National Park may disappear by the year 2030, Harrison Glacier lost only 9 percent of its surface area in the 40-year period between 1966 and 2005 and will likely still exist well beyond 2030. Compared to many of the vanishing glaciers in Glacier National Park, Harrison Glacier has a much higher altitude accumulation zone (approximately ) which has allowed it to maintain some equilibrium in its glacier mass balance. Comparing images of the glacier taken in 1913 with those from 2009, indicates that the glacier has experienced thinning and retreat.
Document 14: Glacier View Dam: Glacier View Dam was proposed in 1943 on the North Fork of the Flathead River, on the western border of Glacier National Park in Montana. The tall dam, to be designed and constructed by the U.S. Army Corps of Engineers in the canyon between Huckleberry Mountain and Glacier View Mountain, would have flooded in excess of of the park. In the face of determined opposition from the National Park Service and conservation groups, the dam was never built.
Document 15: Shepard Glacier: Shepard Glacier is a glacier remnant (glacieret) In Glacier National Park in the U.S. state of Montana. The glacieret is immediately southeast of Cathedral Peak. Shepard Glacier was one of a number of glaciers that have been documented by the United States Geological Service (USGS) to have retreated significantly in Glacier National Park. Shepard Glacier was measured in 2009 to have decreased to less than , considered to be a minimal size to qualify as being considered an active glacier. Between 1966 and 2005, Shepard Glacier lost 56 percent of its surface area.
