1. Materials about the Semenov Peak area

Semenov Peak (5816 m), one of the most famous peaks in the Central Tian Shan, is located in the eastern part of the Sarydzhas ridge in the upper reaches of the eponymous glacier. The huge glaciated mass of Semenov Peak is the highest point of this ridge. East of Semenov Peak, in the Sarydzhas ridge, rises a two-headed peak (5437 m) - an important orographic node of Tian Shan. Here, the Terskey Alatau ridge (under the name of Katta-Ashutor) connects with Sarydzhas. The orography of the Semenov Peak area is incorrectly shown on:

• the map of military topographers from 1943
• in the articles by A. Letavet and Timoshev "Conquest of the Marble Wall Peak"
• in the diagram by Nozdryukhin, etc. The true structure of this area was first shown on the diagram by V. Kolokolnikov (1953). And to the west (approximately 5 km away) is the unnamed peak "5488 m", which is also a photographic node (the Adyr-Tor ridge branches off from it, serving as a watershed between the Semenov and Mushketov glaciers). In addition to the two main ridges mentioned, a powerful southeast spur branches off from the peak, from which in turn further branch off:
