Question: Like the Baltoro Kangri, K12 is present in what range of mountains?

full_context: Document 1: Abruzzi Glacier: The Abruzzi Glacier (Urdu: ‎ ) is a glacier north of the Baltoro Kangri peak in Gilgit-Baltistan, Pakistan. The glacier joins the Baltoro Glacier (one of the largest glaciers outside the polar region) that flows northwest in the beginning and then turns westward. The glacier provides superb views of K2, highest peak in Pakistan.
Document 2: Ghent Kangri: Ghent Kangri (or Mount Ghent, Ghaint I) is a high peak near the north end of the Saltoro Mountains, a subrange of the Karakoram range. It is located west of the Siachen Glacier in an area under Pakistan control, but very close to the Actual Ground Position Line with India.
Document 3: K12 (mountain): Surveyed as K12, this mountain is in the Saltoro Muztagh which is a subrange of the Karakoram range in the Siachen region, near Jammu and Kashmir. It lies near the Line of Control. Its name comes from its designation given during the original survey of the Karakoram range.
Document 4: Baltoro Kangri: Baltoro Kangri (Urdu: بلتورو کنگری‎ ; also known as the Golden Throne) is a mountain of the Karakoram mountain range in Gilgit-Baltistan, Pakistan. Baltoro Kangri is the 82nd highest mountain in the world with an elevation of 7312 m . It lies to the south of the Gasherbrums and east of Chogolisa Peak (7,665 m). The huge Baltoro Glacier (which is one of the largest glaciers outside polar regions) rises from the foot of Baltoro Kangri. In the north of Baltoro Kangri is the Abruzzi Glacier.
Document 5: Kashmir: Kashmir is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term "Kashmir" denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. Today, it denotes a larger area that includes the Indian-administered territory of Jammu and Kashmir (subdivided into Jammu, Kashmir, and Ladakh divisions), the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan, and Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract.
Document 6: K6 (mountain): Surveyed as K6 (Urdu: کے 6‎ ), but also known as Baltistan Peak. This is a notable peak of the Masherbrum Mountains, a subrange of the Karakoram mountain range in Gilgit Baltistan region of Pakistan. Despite being much lower than its sister mountains, the Eight-thousanders and high 7000m peaks such as Masherbrum, it has huge, steep faces, and great relief above the nearby valleys.
Document 7: Masherbrum: Masherbrum (Urdu: ‎ ; formerly known as K1) is located in the Ghanche District, Gilgit Baltistan of Pakistan. At 7821 m it is the 22nd highest mountain in the world and the 9th highest in Pakistan. It was the first mapped peak in the Karakoram mountain range, hence the designation "K1".
Document 8: Biarchedi: Biarchedi Peak is a mountain peak on the south of the Baltoro Glacier in Pakistan. In its southwest is Masherbrum (7,806 m) and in its east is the Mitre Peak (6,010 m). In its northeast is the Biarchedi Glacier that flows north into the Baltoro Glacier.
Document 9: Sia Kangri: Sia Kangri (7,442 m, 24,370 ft) is a mountain in the Baltoro Muztagh in the Karakoram. Its summit is the tripoint of territory controlled by India, China and Pakistan where the Actual Ground Position Line between Indian and Pakistani forces meets Chinese-controlled territory. Territories on all sides are disputed. The land immediately to the southwest of the peak is claimed by both Pakistan and India and controlled by Pakistan. The land to the northeast is part of the Trans Karakoram Tract, controlled by China under a 1963 border agreement with Pakistan but claimed by India. The land to the southeast is claimed by Pakistan and India, but controlled by India, as a part of its Siachen glacier territory.
Document 10: Gasherbrum: Gasherbrum (Urdu: گاشر برم‎ ) is a remote group of peaks located at the northeastern end of the Baltoro Glacier in the Karakoram range of the Himalaya on the border of the Chinese-administered Shaksgam Valley and the Gilgit-Baltistan territory of Pakistan. The massif contains three of the world's 8,000 metre peaks (if Broad Peak is included). Although the word "Gasherbrum" is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of Gasherbrum IV, it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain".
Document 11: Baltoro Glacier: The Baltoro Glacier (Urdu: ‎ ), at 63 km in length, is one of the longest glaciers outside the polar regions. It is located in the Gilgit-Baltistan region (the northernmost political entity of Pakistan). It runs through part of the Karakoram mountain range. The Baltoro Muztagh lies to the south and east of the glacier, while the Masherbrum Mountains lie to the south. At 8,611 m (28,251 ft), K2 is the highest mountain in the region, and three others within 20 km top 8,000 m.
Document 12: Gasherbrum I: Gasherbrum I (Urdu: ‎ ; ), surveyed as K5 and also known as Hidden Peak, is the 11th highest mountain in the world at 8080 m above sea level. It is located on the Pakistani–Chinese border in Gilgit–Baltistan region of Pakistan and Xinjiang region of China. Gasherbrum I is part of the Gasherbrum massif, located in the Karakoram region of the Himalaya. Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain."
Document 13: Rimo Muztagh: The Rimo Muztagh is one of the most remote subranges of the Karakoram range. The southern part of Rimo Muztagh is in the Kashmir portion of far northwestern India, also claimed by Pakistan. The northern half, including the Rimo massif, is in the Siachen area (territory controlled by India). It is far from major towns, and close to the militarily sensitive Siachen Glacier, so it has seen little exploration or climbing activity compared to, for example, the nearby Baltoro Muztagh. The highest peak is Mamostong Kangri, 7,516 metres (24,659 feet).
Document 14: Saltoro Kangri: Saltoro Kangri (Urdu: ‎ ) is the highest peak of the Saltoro Mountains, better known as the Saltoro Range, which is a part of the Karakoram. It is the 31st highest mountain in the world, but it is in a very remote location deep in the Karakoram. It is located on the Actual Ground Position Line between Indian controlled territory in the Siachen region and Pakistani-controlled territory west of the Saltoro Range.
Document 15: Muztagh Tower: Muztagh Tower (also: Mustagh Tower; "Muztagh": ice tower), is a mountain in the Baltoro Muztagh, part of the Karakoram range in Baltistan on the border of the Gilgit–Baltistan region of Pakistan and the Xinjiang Uyghur Autonomous Region of China. It stands between the basins of the Baltoro and Sarpo Laggo glaciers.
