Question: Horse Creek begins in which North American mountain range?

full_context: Document 1: Horse Creek (McKenzie River): Horse Creek is a tributary of the McKenzie River in near the unincorporated community of McKenzie Bridge in Lane County in the U.S. state of Oregon. It begins in the Cascade Range in the Three Sisters Wilderness of the Willamette National Forest. Its headwaters are near the Deschutes County border and the Pacific Crest Trail. It flows generally northwest to meet the river about 65 mi upstream of the McKenzie's confluence with the Willamette River.
Document 2: Level Mountain: Level Mountain is an immense volcanic massif in the Northern Interior of British Columbia, Canada. It is 50 km north-northwest of Telegraph Creek and 60 km west of Dease Lake on the Nahlin Plateau. With a maximum elevation of 2166 m , it is the third highest of five large volcanic complexes in the Northern Cordilleran Volcanic Province (NCVP). Much of the massif is gently-sloping; when measured from its base, Level Mountain is about 1100 m tall, slightly taller than its neighbour to the northwest, Heart Peaks. The lower broader half of Level Mountain consists of a shield-like edifice while its upper half has a more steep, jagged profile. Its summit is dominated by the Level Mountain Range, a small mountain range with prominent peaks cut by deep valleys. These valleys serve as a radial drainage for several small streams that flow across the volcano. Meszah Peak is the only named peak in the Level Mountain Range.
Document 3: Dead Indian Creek (Oregon): Dead Indian Creek is a tributary of South Fork Little Butte Creek in Jackson County, in the U.S. state of Oregon. It flows generally north through the Rogue River – Siskiyou National Forest in the Cascade Range east of Medford. The creek begins at 2562 ft above sea level near Howard Prairie Lake and enters the South Fork at Camp Latgawa. The South Fork flows northwest to meet the North Fork near Lake Creek; combined they form Little Butte Creek, a tributary of the Rogue River.
Document 4: Drift Creek (Siletz Bay): Drift Creek is a tributary, about 18 mi long, of Siletz Bay in the U.S. state of Oregon. The creek begins near Stott Mountain in the Central Oregon Coast Range in Lincoln County and follows a winding course generally west through the Siuslaw National Forest to enter the bay south of Lincoln City on the Pacific Ocean. It passes under U.S. Route 101 just before reaching the bay.
Document 5: Pacific Northwest: The Pacific Northwest (in the United States, commonly abbreviated as PNW), sometimes referred to as Cascadia, is a geographic region in western North America bounded by the Pacific Ocean to the west and (loosely) by the Cascade Mountain Range on the east. Though no agreed boundary exists, a common conception includes the U.S. states of Oregon and Washington and the Canadian province of British Columbia. Broader conceptions reach north into Alaska and Yukon, south into northern California and east to the Continental Divide, thus including Idaho, Western Montana, and western Wyoming. Idaho, Wyoming, and Montana are more accurately termed the Inland Northwest (INW), as the climate, folia, fauna, and politics are different than in the Pacific Northwest, as well as a different time zone in all but North Idaho. Narrower conceptions may be limited to the northwestern US or to the coastal areas west of the Cascade and Coast mountains. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, geography, society, and other factors.
Document 6: Cascade Volcanoes: The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over 700 mi . The arc has formed due to subduction along the Cascadia subduction zone. Although taking its name from the Cascade Range, this term is a geologic grouping rather than a geographic one, and the Cascade Volcanoes extend north into the Coast Mountains, past the Fraser River which is the northward limit of the Cascade Range proper.
Document 7: West Fork Salmon River (Clackamas County, Oregon): The West Fork Salmon River is a tributary of the Salmon River in Clackamas County in the U.S. state of Oregon. Beginning near Timberline Lodge at the base of Mount Hood in the Cascade Range, it flows generally south to meet the main stem Salmon near Red Top Meadow, slightly south of the intersection of U.S. Route 26 and Oregon Route 35. The entire course of the river, which has no named tributaries, lies within the Mount Hood National Forest.
Document 8: Coast Mountains: The Coast Mountains are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordilleraa Spanish term for an extensive chain of mountain rangesthat consists of an almost continuous sequence of mountain ranges that form the western backbone of North America, Central America, South America and Antarctica.
Document 9: Cascade Range: The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at 14411 ft .
Document 10: Mount Baker: Mount Baker (Lummi: "Qwú’mə Kwəlshéːn "; Nooksack: "Kw’eq Smaenit" or "Kwelshán "), also known as Koma Kulshan or simply Kulshan, is an active glaciated andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount Saint Helens. About 31 mi due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field. While volcanism has persisted here for some 1.5 million years, the current glaciated cone is likely no more than 140,000 years old, and possibly no older than 80–90,000 years. Older volcanic edifices have mostly eroded away due to glaciation.
Document 11: North Fork Breitenbush River: The North Fork Breitenbush River is a tributary of the Breitenbush River in the U.S. state of Oregon. It begins at Papoose Lakes near Breitenbush Lake in the Cascade Range north of Mount Jefferson and flows generally northwest and west through the Mount Hood National Forest, Olallie Scenic Area, Mount Jefferson Wilderness, and Willamette National Forest. It merges with the South Fork Breitenbush River to form the Breitenbush River main stem slightly upstream of Breitenbush Hot Springs.
Document 12: Monashee Mountains: The Monashee Mountains are a mountain range lying mostly in British Columbia, Canada, extending into the U.S. state of Washington. They stretch 530 km from north to south and 150 km from east to west. They are a sub-range of the Columbia Mountains. They are limited on the eastern side by the Columbia River and Arrow Lakes, beyond which lie the Selkirk Mountains, and by the upper North Thompson River and the Interior Plateau on the west. The northern end of the range is at the southern end of the Robson Valley just south of the town of Valemount. The southern extremity of the range is in Washington State, where the Kettle River Range reaches just down to the confluence of the Kettle River and the Columbia, and also farther west to the southern extremity of the Okanagan Highland (spelled Okanogan Highland in the US) just northeast of the confluence of the Okanogan and Columbia rivers at Brewster and Bridgeport.
Document 13: Horse Creek Bridge (McKenzie Bridge, Oregon): The Horse Creek Bridge was a covered bridge near the unincorporated community of McKenzie Bridge in Lane County in the U.S. state of Oregon. Built in 1930, the structure, 105 ft long, carried Horse Creek Road over Horse Creek. The creek is a tributary of the McKenzie River.
Document 14: South Fork Breitenbush River: The South Fork Breitenbush River is a 10 mi tributary of the Breitenbush River in the U.S. state of Oregon. The river flows generally northwest from Russell Lake in the Mount Jefferson Wilderness of the Cascade Range to near Breitenbush Hot Springs, where it merges with the North Fork Breitenbush River to form the main stem.
Document 15: Horse Creek, Wyoming: Horse Creek is an unincorporated community in western Laramie County, Wyoming, United States. It lies between Horse Creek to the north, and the South Fork of Horse Creek to the south, along WYO 211 northwest of the city of Cheyenne, the county seat of Laramie County. Its elevation is 6,506 feet (1,983 m). Although Horse Creek is unincorporated, it has a post office, with the ZIP code of 82061. As of the 2010 census, Horse Creek had an estimated population of 39.
