Roopkund is a high altitude glacial lake in the Uttarakhand state of India. It lies in the lap of Trishul massif. Located in the Himalayas, the area around the lake is uninhabited and is roughly at an altitude of 5,020 metres (16,470 ft), surrounded by rock-strewn glaciers and snow-clad mountains. Roopkund is a popular trekking destination. The size of the lake varies substantially, but it is seldom more than 40 metres in diameter, and is frozen in the winter.

Trisul is a group of three Himalayan mountain peaks of western Kumaun, Uttarakhand, with the highest reaching 7120m. The three peaks resemble a trident - in Sanskrit, Trishula, trident, is the weapon of Shiva. The Trishul group forms the southwest corner of the ring of peaks enclosing the Nanda Devi Sanctuary, about 15 kilometres (9 mi) west-southwest of Nanda Devi itself. The main peak, Trisul I, was the first peak over 7,000 m (22,970 ft) to have ever been climbed, in 1907.
