Question: Which mountain is higher, Masherbrum or Khunyang Chhish?
Context: 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. Yukshin Gardan Sar (Urdu: ‎ ) is a high peak of the Hispar Muztagh, a subrange of the Karakoram range in Pakistan.  Its height is also often given as 7,469 m (24,505 ft) or 7,641 m (25,069 ft).  It lies about 15 km (9 mi) northeast of Khunyang Chhish and 5 km (3 mi) northwest of Kanjut Sar.  It is flanked on the northwest by the Yazghil Glacier and on the northeast by the Yukshin Gardan Glacier; both drain into the Shimshal River. Khunyang Chhish or Kunyang Chhish (Urdu: ‎ )is the second-highest mountain in the Hispar Muztagh, a subrange of the Karakoram mountains of Pakistan.  Alternate variations of the name include Kunyang Kish and Khiangyang Kish, among others.  Its height, also sometimes given as 7823 m , is ranked 21st in the world and 8th in Pakistan. 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. Pumari Chhish (Urdu: ‎ ), (or Pumarikish, Peak 11) is a high peak of the Hispar Muztagh, a subrange of the Karakoram range.  It lies about 4 km east of Khunyang Chhish, in the heart of the Hispar, north of the Hispar Glacier. Shingu Charpa is a mountain in the Hushe Region in Pakistan.  It is a 5800 meter Karakorum spire located in Masherbrum massif in Nangma valley. Kunyang or Khunyang Chhish East is a 7400m mountain in the Khunyang Chhish massive (a subrange of the Karakoram mountains of Pakistan).  It is separated by a 7160 m pass from the main summit 2 km to the West and has a 2,700 m Southwest face.  On July 18, 2013 Hansjörg Auer, Matthias Auer and Simon Anthamatten made the first ascent over this wall, which had been widely regarded as one of the great remaining problems in alpinism. Burji La (or Burji Pass) is a natural pass in mountains between Skardu and Deosai National Park in Gilgit Baltistan, Pakistan.  Its elevation is 4816 meters.  It is famous especially for its beautiful panoramic view of so many mountain peaks, including that of K2, Nanga Parbat, Masherbrum, Chogolisa, Laila Peak, Golden Peak, Gasherbrum I, Gasherbrum II, Gasherbrum IV and a part of Broad Peak mountain. 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. 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".
