Input: Context_1 : Rila (Bulgarian: , ] ) is a mountain range in southwestern Bulgaria and the highest mountain range of Bulgaria and the Balkans, with its highest peak being Musala at 2,925 m. The massif is also the sixth highest mountain in Europe (when each mountain is represented by its highest peak only), coming after the Caucasus, the Alps, Sierra Nevada, the Pyrenees and Mount Etna, and the highest between the Alps and the Caucasus. More than one-third of the mountain is occupied by the Rila National Park, the rest lies within the Rila Monastery Nature Park. Context_2 : The Chehalem Mountains are a mountain range located in the Willamette Valley in the U.S. state of Oregon. Forming the southern boundary of the Tualatin Valley, the Chehalems are the highest mountains in the Willamette Valley. Composed of a single land mass that was uplifted by tectonic forces, the mountain range includes several spurs and ridges such as Parrett Mountain, Ribbon Ridge, and Bald Peak. The range extends from the Willamette River east of Newberg northwest to the foothills of the Oregon Coast Range south of Forest Grove. The highest peak in the Chehalem Mountain Range is Bald Peak, rising to 1629 ft , which is also the highest peak point within the Willamette Valley. Context_3 : Crabtree Creek is a tributary of the South Santiam River in Linn County in the U.S. state of Oregon. It begins in the western foothills of the Cascade Range at Crabtree Mountain near Crabtree Lake. From there it flows generally west to meet the larger stream about 3 mi upstream of where the South Santiam merges with the North Santiam River to form the Santiam River. Context_4 : Roaring River is a tributary of Crabtree Creek in Linn County in the U.S. state of Oregon. It begins in the western foothills of the Cascade Range near Snow Peak. From there it flows generally west to meet Crabtree Creek at Larwood Wayside Park, north of Lacomb, about 16 mi upstream of where the creek meets the South Santiam River east of Albany. The only named tributary of Roaring River is Milky Fork, which enters from the left near Roaring River Park. Context_5 : 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 . Context_6 : The Wind River Range (or "Winds" for short), is a mountain range of the Rocky Mountains in western Wyoming in the United States. The range runs roughly NW-SE for approximately 100miles (161km). The Continental Divide follows the crest of the range and includes Gannett Peak, which at 13,804feet (4,207m), is the highest peak in Wyoming. There are more than 40 other named peaks in excess of 13,000feet (3,962m). 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. Two large National Forests including three wilderness areas encompass most of the mountain range. Shoshone National Forest is on the eastern side of the continental divide while Bridger-Teton National Forest is on the west. Both National Forests and the entire mountain range are an integral part of the Greater Yellowstone Ecosystem. Portions of the range are also inside the Wind River Indian Reservation. Context_7 : Vardousia (Greek: ) is a mountain in northwestern Phocis and southwestern Phthiotis, Greece. Its highest peak, Korakas (Greek: ) reaches 2495 m above sea level, making it the second-tallest summit in Central Greece after Giona. It is a southern extension of the Pindus mountains. It is divided into three main parts: Northern Vardousia, whose highest peak is Sinani at 2,059 m , the very steep Western Vardousia, whose highest peak is "Soufles" at 2,300 m , and Southern Vardousia, with the highest peak of "Korakas". The whole range measures about 25 km from north to south. Context_8 : The Salmon River Mountains are a major mountain range covering most of the central part of the U.S. state of Idaho. The range is over 120 mi long and its boundaries are usually defined by the Salmon River and its large tributary forks. Part of the central Rocky Mountains, the entire range lies west of the Continental Divide of the Americas and drains to the Snake River. The highest peak is White Mountain, at 10442 ft above sea level. There are five peaks over 10000 ft high, and there are three major subranges defined by other forks of the Salmon River: the West, Central and East Salmon River Mountains. Context_9 : Argonaut Peak is a tall mountain in the Cascade Range in the U.S. state of Washington. Part of the Stuart Range part of the Wenatchee subrange of the Cascades, it is within the Alpine Lakes Wilderness of the Wenatchee National Forest and part of the region known as The Enchantments. At 8453 ft in elevation it is the 65th highest peak in Washington. Located on the crest between Colchuck Peak and Sherpa Peak, Argonaut Peak has a southeast and a west summit of almost identical height, with the west being the true summit. There is a prominent southeast spire. Its southern side slopes down to the valley of Ingalls Creek. The north and northeast sides of Argonaut stand high above a branch of Mountaineer Creek, a tributary of Icicle Creek. Argonaut Peak is 1.7 mi west of Isolation Lake and 1.8 mi east of Mount Stuart. Context_10 : The Haiyang Mountains (), in ancient times known as ""Yanghai Mountains"" () form a mountain range in the northeastern Guangxi separating West River drainage basin of the Xi River from the Xiang River drainage basin of the Yangtze River. The mountain range is located between Yuecheng Mountains and Dupang Mountains of Nanling Mountain Range, it is a major mountain range in Guilin, Guanxi, China. It runs south to north through Guanyang, Quanzhou, Xing'an, Lingchuan, Gongcheng and Yangshuo six counties. With a width of 35 km to 40 km , the Haiyang Mountains stretch more than 97 km from Yangshuo to Quanzhou. The highest peak is "Baogai Hill" () with an elevation of 1935.8 m . fact_1 : Crabtree Creek is a tributary of the South Santiam River in Linn County in the U.S. state of Oregon. fact_2 : It begins in the western foothills of the Cascade Range at Crabtree Mountain near Crabtree Lake. fact_3 : 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. fact_4 : The highest peak in the range is Mount Rainier in Washington at 14411 ft . Answer: 14411 ft
