Glen Coe

Glen Coe is a glen of volcanic origins, in the Highlands of Scotland. It lies in the north of the county of Argyll, close to the border with the historic province of Lochaber, within the modern council area of Highland. The scenic beauty of the glen has led to its inclusion in the Ben Nevis and Glen Coe National Scenic Area, one of 40 such areas in Scotland. A review of the national scenic areas by Scottish Natural Heritage in 2010 made reference to the "soaring, dramatic splendour of Glen Coe", and "the suddenness of the transition between high mountain pass and the lightly wooded strath" in the lower glen. It also described the journey through the glen on the main A82 road as "one of the classic Highland journeys". The main settlement is the village of Glencoe located at the foot of the glen. The glen is regarded as the home of Scottish mountaineering and is popular with hillwalkers and climbers.

Yarlung Tsangpo Grand Canyon

The Yarlung Tsangpo Grand Canyon or Yarlung Zangbo Grand Canyon or simply the Tsangpo Canyon, Brahmaputra Canyon or Tsangpo Gorge, along the Yarlung Tsangpo River in Tibet Autonomous Region, China, is the deepest canyon in the world, and at 504.6 km is slightly longer than the Grand Canyon in the United States, making it one of the world's largest. The Yarlung Tsangpo originates near Mount Kailash and runs east for about 1700 km, draining a northern section of the Himalayas before it enters the gorge just downstream of Pei, Tibet near the settlement of Zhibe. The canyon has a length of about 240 km as the gorge bends around Mount Namcha Barwa and cuts its way through the eastern Himalayan range. Its waters drop from about 2,900 m near Pei to about 1,500 m at the end of the Upper Gorge where the Po Tsangpo River enters. The river continues through the Lower Gorge to the Indian border at an elevation of 660 m. The river then enters Arunachal Pradesh and eventually becomes the Brahmaputra.
