Thalay Sagar

Thalay Sagar is a 6,904-meter peak in the western Garhwal Himalayas featuring steep rock walls and a demanding north face within the Gangotri massif. The summit sits at a considerable height in this high-altitude mountain chain.

The first successful ascent reached the summit in June 1979 when Roy Kligfield, John Thackray, and Pete Thexton climbed through the northwest couloir. This achievement opened the route for future mountaineering expeditions in the region.

The mountain stands near Gangotri, a sacred pilgrimage site where the Bhagirathi River originates, making it part of a spiritually significant region for Hindu traditions.

The climbing season runs from June through September, requiring around 40 days of expedition time from Delhi. Proper mountaineering experience and acclimatization are necessary for this high-altitude ascent.

A notable shale band near the peak creates technical climbing challenges due to unstable rock composition that climbers must carefully navigate. This geological feature makes the final push toward the summit significantly more demanding than expected.
