Sarpo Laggo Glacier, Mountain glacier in Xinjiang, China

Sarpo Laggo Glacier is a large ice mass in the Karakoram range that extends through the Baltoro Muztagh mountains in Xinjiang. The glacier covers a substantial area and connects with surrounding ice formations to create a complex frozen landscape.

The glacier is named after Francis Younghusband, the first person to cross the Old Mustagh Pass and enter the Sarpo Laggo region. His route linked the Baltoro Glacier on the Pakistani side with the Sarpo Laggo Glacier, and the pass lies northeast of the Trango Towers. Another glacier nearby, the Younghusband Glacier (Biango Glacier), also bears his name and flows from Muztagh Tower toward the Baltoro Glacier.

The name Sarpo Laggo means "young husband" in the local Balti tongue, while the glacier itself is named after Francis Younghusband, the first person to cross the Old Mustagh Pass into the region. Three pass crossings at its head — the Western Muztagh, Sarpo Laggo and Eastern Muztagh passes — link the Indus valley with the Yarkand area of China.

Reaching the glacier requires a demanding trek from Kashgar through mountainous terrain along the Karakoram Highway. Visitors need to prepare for high altitude conditions and should travel with local guides and proper equipment suited to this remote location.

The glacier is part of a connected system of nearby ice masses, including the neighboring Younghusband Glacier, showing how multiple glaciers interact in this high-altitude region. This network reveals the way different frozen formations influence each other across the broader landscape of the Karakoram.
