Short summary
Photosynthetic microbes can darken snow and ice, accelerating glacier melt. While well studied in the Arctic, this process remains poorly understood in dust-rich Central Asian glaciers. We investigated microbial communities on a Tien Shan glacier across a melt season. Snow algae dominated early, but cyanobacteria prevailed once bare ice was exposed. Unlike the Arctic, typical glacier algae were absent, indicating a distinct ecosystem that may influence regional melting and water resources.
