Trishul Peak stands at an elevation of 23,490 ft and is counted among the ski-friendly ranges of Auli. It is situated in Kumaon in the state of Uttarakhand near the district of Bageshwar. The Trishul Mountains form the south-east corner of the ring of peaks encircling the Nanda Devi Sanctuary. It is named after the trident of Lord Shiva (Hindu God).Initially, Trishul and other peaks were used as the training area for the ski-equipped patrolling officers of the Indo-Tibetan Border Police Force. At the bottom of the slopes of the peak lies a lake, named the Roopkund. It is also known as the Mystery Lake because of the discovery of around 600 skeletal remains of humans and horses here. The Trishul Mountains can be viewed from Kausani and Bedini Bugyal.
