141. Lyalver — Tetnuld (the route is combined, by I. Shintlmeister, category 4B difficulty level, fig. 20, 22). From the village of Zhabishi, ascend via the trail on the left bank of the Tsanner River and, bypassing the first step of the icefall, descend onto the glacier. Along the left side of the glacier, approach the second step, which is traversed on its left side. The third step is also passed on the left via the snowy-icy slopes of the spur, and beyond it, exit onto the upper plateau of the Tsanner Glacier. On the moraine, in the center of the upper plateau, closer to the slopes of Tikhtengen on the Tsanner площадках (Tsanner sites), set up the initial bivouac. From the village of Zhabishi, it takes 10–14 hours. From the bivouac site, turn right
