The prominent landmarks around the Stak valley are: Kutia Lungma Glacier, Goropha Glacier (which joins the Chogo Lungma Glacier), Haramosh Peak (7,397 m, 24,270 ft), Pharabar Peak (60,321 m 20,740 ft), Stak-La (Stak Mountain Pass 4,601 m, 15,491 ft) and some other peaks (Shinka, Mashika, Korang Kar) which are about 6,000 m (20,000 ft). The Stak River originates from the Stak-La and joins by Goropha, Kutia and Tooklano Streams and falls in Indus River after completing a course of about 30 km. The Stak River bisects the Stak Valley into two halves. One half starts from Rgialmokaza to Skangbudas and the other side starts from Khirzang to Tookla. Tookla is the last village of Stak, which is partly destroyed by a massive flood in 1999 which caused a huge destruction in the area, destroying the Gamba Tookla completely and Gongma Tookla partially. According to Geologists most of the villages are formed by the moraines, although the valley is one of the fertile valleys of the Roundu Subdivision
