What is "shivling"

Shivling is a mountain at tapovan in the Gangotri Group of peaks in the western Garhwal Himalaya, near the snout of the Gangotri Glacier. It lies in the northern Indian state of Uttarakhand, south of the Hindu holy site of Gaumukh (the source of the Bhagirathi River). Its name refers to its status as a sacred symbol - Shiva Linga. It was called " Matterhorn Peak" by early European visitors because of its similarity in appearance to that Alpine peak. While not of locally great elevation, it is a dramatic rock peak, and most visually striking peak seen from Gaumukh; that and the difficulty of the climb make it a famed prize for mountaineers.
