Question: The Missouri river has a tributary that originates from what peak in the Absaroka Range?

full_context: Document 1: Fremont Peak (Wyoming): Fremont Peak is the third highest peak in Wyoming and straddles the boundary between Fremont and Sublette counties. It is named for American explorer John C. Fremont who climbed the peak with Charles Preuss and Johnny Janisse on 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 range.
Document 2: Absaroka Range: The Absaroka Range ( or ) is a sub-range of the Rocky Mountains in the United States. The range stretches about 150 mi (240 km) across the Montana-Wyoming border, and 75 miles at its widest, forming the eastern boundary of Yellowstone National Park along Paradise Valley (Montana), and the western side of the Bighorn Basin. The range borders the Beartooth Mountains to the north and the Wind River Range to the south. The northern edge of the range rests along I-90 and Livingston, Montana. The highest peak in the range is Francs Peak, located in Wyoming at 13153 ft . There are 46 other peaks over 12000 ft .
Document 3: Younts Peak: Younts Peak is a peak in the Absaroka Range in northwestern Wyoming in the United States and the highest point in the Teton Wilderness. The Yellowstone River is formed near the peak from two streams that rise on the northern and southern ridges of the peak and join at the base of the western ridge. The peak summit itself can be hiked, but accessing the peak is difficult due to its remoteness. The peak was named after Harry Yount, a hunter and guide considered to be the first ranger in Yellowstone National Park.
Document 4: Tongue River (Montana): The Tongue River is a tributary of the Yellowstone River, approximately 265 mi (426 km) long, in the U.S. states of Wyoming and Montana. The Tongue rises in Wyoming in the Big Horn Mountains, flows through northern Wyoming and southeastern Montana and empties into the Yellowstone River at Miles City, Montana. Most of the course of the river is through the beautiful and varied landscapes of eastern Montana, including the Tongue River Canyon, the Tongue River breaks, the pine hills of southern Montana, and the buttes and grasslands that were formerly the home of vast migratory herds of American bison. The Tongue River watershed encompasses parts of the Cheyenne and Crow Reservations. The Headwaters lie on the Big Horn National Forest, and the watershed encompasses the Ashland Ranger District of the Custer National Forest.
Document 5: Missouri River: The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2341 mi before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km), which includes parts of ten U.S. states and two Canadian provinces. When combined with the lower Mississippi River, it forms the world's fourth longest river system.
Document 6: Missouri River Valley: The Missouri River Valley outlines the journey of the Missouri River from its headwaters where the Madison, Jefferson and Gallatin Rivers flow together in Montana to its confluence with the Mississippi River in the State of Missouri. At 2300 mi long the valley drains one-sixth of the United States, and is the longest river valley on the North American continent. The valley in the Missouri River basin includes river bottoms and floodplains.
Document 7: Absaroka-Beartooth Wilderness: Absaroka-Beartooth Wilderness was created from existing National Forest lands in 1978 and is located in Montana and Wyoming, United States. The wilderness is partly in Gallatin, Custer and Shoshone National Forests and is composed of 944,000 acre . The wilderness encompasses two distinct mountain ranges, namely the Beartooth and Absaroka ranges. These ranges are completely distinct geologically speaking with the Absarokas composed primarily of volcanic (or extrusive) and metamorphic rock, while the Beartooths are made up almost entirely of granitic rocks. The Absarokas are noted for their dark and craggy appearance, lush and heavily forested valleys and abundant wildlife. The highest peak in the range, located in Wyoming, is Francs Peak at 13,153 ft . The Beartooths are more alpine with huge treeless plateaus and the highest peak in the state of Montana (Granite Peak 12,799 ft ). The wilderness contains 30 peaks over 12,000 ft . The wilderness is an integral part of the 20 e6acre Greater Yellowstone Ecosystem and borders Yellowstone National Park.
Document 8: Teton Wilderness: Teton Wilderness is located in Wyoming, United States. Created in 1964, the Teton Wilderness is located within Bridger-Teton National Forest and consists of 585,238 acres (2,370 km). The wilderness is bordered on the north by Yellowstone National Park and to the west by Grand Teton National Park and the John D. Rockefeller, Jr. Memorial Parkway. The Washakie Wilderness is to the east and the remainder of Bridger-Teton National Forest is to the south. The Teton Wilderness is a part of the 20 million acre (81,000 km) Greater Yellowstone Ecosystem. Among many other features, Teton Wilderness is notable for having the most remote location (farthest from any road) of any place in the contiguous 48 states of the US. This location occurs very close to Bridger Lake, near the confluence of the Thorofare and Yellowstone Rivers, not far from the USFS Hawk's Rest Ranger Station.
Document 9: Index Peak (Wyoming): Index Peak, el. 10709 ft , is a prominent mountain peak in the Absaroka Range in Park County, Wyoming. The peak is visible from US Route 212, the Beartooth Highway just east of the Northeast Entrance Station to Yellowstone National Park. Pilot Peak rises just south of Index Peak.
Document 10: Marias River: The Marias River is a tributary of the Missouri River, approximately 210 mi (338 km) long, in the U.S. state of Montana. It is formed in Glacier County, in northwestern Montana, by the confluence of the Cut Bank Creek and the Two Medicine River. It flows east, through Lake Elwell, formed by the Tiber Dam, then southeast, receiving the Teton River at Loma, 2 mi. (3.2 km) above its confluence with the Missouri.
Document 11: Red Rock River (Montana): The Red Rock River is a roughly 70 mi river in southwestern Montana in the United States. Its drainage basin covers over 1548 mi2 . Its furthest tributary, Hell Roaring Creek, originates in the Beaverhead National Forest within a few hundred meters of the North American Continental Divide and Montana-Idaho border near Brower's Spring, at an elevation of about 9100 ft . Brower's Spring is near the furthest headwaters of the Missouri River, one of the major watercourses of the central United States. The drainage flows north and west with its name changing to "Red Rock Creek" into the Red Rock Lakes in the middle of a wide grassy valley; the Red Rock River issues from the west side of Lower Red Rock Lake. It flows west, receiving many tributaries such as Peet Creek and Long Creek, widening into the Lima Reservoir and then passing through a canyon, which ends near Lima, Montana. From there, it flows northwest through a valley, passing Kidd and Red Rock, and into Clark Canyon Reservoir. Under the waters of the lake was once the confluence of the Red Rock and Horse Prairie Creek, forming the Beaverhead River, a tributary of the Jefferson River, in turn a headwater of the Missouri River.
Document 12: Druid Peak: Druid Peak (elevation 9577 ft ) is a moderate domed peak on the southern flank of the Absaroka Range in Yellowstone National Park. The peak lies just north of the Lamar River and Soda Butte Creek confluence at the head of the Lamar Valley. Prior to 1885, this summit was named "Soda Hill" by members of the Hayden Geological Survey of 1878 and "Mount Longfellow" or "Longfellows' Peak" by then park superintendent Philetus Norris in 1880. In 1885, members of the Arnold Hague Geological Survey changed the name to Druid Peak for unknown reasons, but some historians believe it may have been the presence of Stonehenge like rock formations on its eastern face that prompted the name.
Document 13: Colter Peak: Colter Peak el. 10640 ft is a mountain peak in the Absaroka Range in the southeastern section of Yellowstone National Park. The peak is named for mountain man John Colter, reputedly the first white man to visit the Yellowstone region. Colter Peak was first ascended in 1870 by Lt. Gustavus Cheyney Doane and Nathaniel P. Langford during the Washburn–Langford–Doane Expedition. Henry D. Washburn, the expedition leader named the peak for Langford and Doane. For unknown reasons, geologist Ferdinand V. Hayden moved those names to peaks farther north in 1871 during the Hayden Geological Survey of 1871. In 1888, Philetus Norris the second park superintendent, named the peak "Mount Forum" for unknown reasons. In 1885, geologist Arnold Hague gave the peak its official name: Colter Peak.
Document 14: Yellowstone River: The Yellowstone River is a tributary of the Missouri River, approximately 692 mi long, in the western United States. Considered the principal tributary of the upper Missouri, the river and its tributaries drain a wide area stretching from the Rocky Mountains in the vicinity of the Yellowstone National Park across the mountains and high plains of southern Montana and northern Wyoming.
Document 15: Powder River (Wyoming and Montana): Powder River is a tributary of the Yellowstone River, approximately 375 mi long in northeastern Wyoming and southeastern Montana in the United States. It drains an area historically known as the Powder River Country on the high plains east of the Bighorn Mountains.
