Gawalong Glacier

The glacier feeds five proglacial lakes, including the milky-turquoise Tso Karpo (pH 7.1–7.4), formed by meltwater enriched with glacial flour.

[3] The glacier's basal sliding velocity peaks at 12 cm/day in summer, monitored by 15 GPS stakes installed by the Chinese Academy of Sciences.

Endemic species include the ice worm (Mesenchytraeus solifugus gawalongensis) and cushion plant Arenaria glacialis.

Access requires permits from Tibet's Forestry Department, with annual visitor limits of 300 to prevent microplastic contamination.
