21. BUBIS — CHANCHAKHI, traverse (combined route, cat. 4B)

Ascent to the summit of Bubis via the normal route (cat. 2B) from the Tsey-Raug pass. Descent from the summit of Bubis along the southeastern snowy ridge to the saddle below the summit of Tbiliza-Mta. Ascent up a new slope (40–45°) to the summit of Tbiliza-Mta. Descent from the summit of Tbiliza-Mta initially along a gentle (30°) snowy ridge, then down an ice and firn slope (120 m, 70°, piton belay!) to the ridge before a large "gendarme". Bypass the large "gendarme" from the left (in the direction of travel) from the north along a steep (60°) firn slope, followed by an ascent (50 m) onto the ridge. Bypass all encountered "gendarmes" from the right (in the direction of travel) and along a heavily damaged rocky ridge to the Tsey–Tbiliza pass. From the pass, ascend to the summit of Chanchakhi via the normal route (cat. 4B). Descent from the summit of Chanchakhi to the Tsey–Tbiliza pass via the normal route (cat. 4B). When traversing the summit of Chanchakhi in full, the category of the Bubis—Chanchakhi traverse is 5A (approximate).
