The central crest area of the ridge is above the snowline. The slopes are cut by short deep transverse gorges with frequent occurrence of glaciers. The range is composed of limestone and schist of Paleozoic age. [1] The landscapes at southern slopes are: Alpian and sub-Alpian at 3,600–3,900 m (11,800–12,800 ft), and Alpine tundra at 3,900–4,300 m (12,800–14,100 ft); at northern slopes: mountain steppes at 2,400–2,700 m (7,900–8,900 ft), mountain meadows at 2,700–3,000 m (8,900–9,800 ft), sub-Alpian and Alpian at 3,400–3,600 m (11,200–11,800 ft), and tundra at 3,800–4,000 m (12,500–13,100 ft); and at western slopes: stony, steppe, sub-Alpian and tundra.

Several rivers taking their rise from the south slopes of the At-Bashy Range form Aksay river, right tributary of Kakshaal River (Toshkan River). Among those rivers are Keng-Suu, Kosh Kara-Tash, Muzdabas, Tuyuk Bogoshtu, Jol Bogoshtu, Kashka-Suu and Tuyz Ashuu. Kara-Koyun River, left tributary of At-Bashy, rises from the northern slopes of the At-Bash Range.
