Sela Pass
The Sela Pass (more appropriately called Se La, as La means Pass) is a high-altitude mountain pass located on the border between the Tawang and West Kameng districts in the Indian state of Arunachal Pradesh. It has an elevation of 4170 m (13,700 ft) and connects the Indian Buddhist town of Tawang to Dirang and Guwahati. The pass carries the National Highway 13 (previously NH 229), connecting Tawang with the rest of India. The pass supports scarce amounts of vegetation and is usually snow-covered to some extent throughout the year. Sela Lake, near the summit of the pass, is one of approximately 101 lakes in the area that are sacred in Tibetan Buddhism. While Sela Pass does get heavy snowfall in winters, it is usually open throughout the year unless landslides or snow require the pass to be shut down temporarily. Sela pass is one of the highest motorable mountain passes in the world

Etymology

During the 1962 Sino-Indian War, Maha Vir Chakra awardee Jaswant Singh Rawat held Chinese Army off at this mountain pass with the help of two local Monpa girls named Sela and Noora. Later, Sela was killed and Noora captured. Rushing from position to position, Rawat held off the enemy for 72 hours until the Chinese captured a local supplier, who told them that they were facing only one fighter. The Chinese then stormed Rawat's position and Rawat was killed. the Indian army built Jaswant Garh  war memorial for Jaswant Singh and the pass, tunnel & lake were named after Sela for her sacrifice. The tunnel is also named after her. Nuranang Falls, 2 km east of Jang, are named after Nura. Geography
