Gyaca Gorge: A Riveting Geological Wonderland Nestled in the western part of Gyaca County, the Gyaca Gorge, carved by the mighty Yarlung Tsangpo River, presents a breathtaking natural spectacle. This gorge, one of the three major geological fault lines along the river’s course, features a narrowest point of just 40 meters, with an elevation around 3500 meters. Stretching over 100 kilometers with a drop of 300 meters, the gorge ascends to Sangri County, forming a dry-hot valley with distinct geographical features.
A Geological Museum in Nature Gyaca Gorge, shaped by the tectonic forces of the Indian and Eurasian plates, boasts a diverse range of geological phenomena. The dramatic landscape of towering mountains and steep slopes makes it a unique ‘geological museum’. The area is not only a marvel of natural beauty but also holds significant scientific interest for its varied geological formations.
Rich Biodiversity and Rare Finds The region is a haven for rare plant species like the red yew and ancient insect species like the wingless order, earning it the reputation of a “gene bank of biological resources”. The Yarlung Tsangpo River, flowing east out of the Gyaca Gorge, widens, revealing a diverse ecosystem along its banks.
The Majestic Waterfalls of Gyaca Gorge The gorge is home to two remarkable waterfalls – the Monk Waterfall and Nyerka Waterfall – and several cascades over 1 meter high. The Yarlung Tsangpo River dramatically breaks at these points, creating multi-tiered waterfalls with a drop of nearly 30 meters. The Nyerka Waterfall, named after the local term meaning “fish get stuck here,” is a sight to behold, where fish often leap out of the water only to be swept over the falls.
Visiting Gyaca Gorge: Tips for Travelers
- Proximity to Gyaca: The gorge is about 5 kilometers from Gyaca County, with the entrance showcasing wide valleys and farmlands, leading to a landscape filled with large stones, shrubs, and sparse pine forests.
- V-shaped Entrance and Hydroelectric Power: At an altitude of 3200 meters, the mouth of Gyaca Gorge houses Tibet’s largest hydroelectric station – Zangmu Hydropower Station. The dam construction has transformed the gorge into a magnificent sight, showcasing the power and beauty of human engineering.
Gyaca Zangmu Grand Bridge: An Architectural Marvel Spanning the Yarlung Tsangpo River, the Gyaca Zangmu Grand Bridge is an engineering feat. As the world’s highest railway steel tube concrete arch bridge, it stands at an elevation of 3350 meters, with a total length of 525.1 meters and a main arch span of 430 meters.
