It is named in honor of the naturalist and geographer who made a significant contribution to the study of Russia, Academician Peter Simon Pallas (Russian Government Resolution No.

Marked on many maps, Pallas Mountain, then an unnamed peak, was rediscovered in 1977 by Timur Ukhinovich Zhalsarayn, a local historian and geography teacher, as the confluence of the Amur, Yenisei, and Lena river systems.

The fifth in this list can rightly be called Baikal, which, although it is a lake, has long been given the title of "Glorious Sea".

In terms of height above sea level (1236 m), it rises no more than 600 meters above the nearby regional center — the city of Chita.

Even in the immediate vicinity of Watershed Mountain there are higher hills, reaching 1279 and 1243 m.[5] The mountain is located 35 km northwest of the city of Chita in the territory of the Ivano-Aleksandrovsky Natural Park (the center is the system of Ivan-Arakhley Lake System).

Between Chita and the Ivan-Arakhley lake system, P. S. Pallas' scheme shows mountains, one of which can be associated with the Amur-Leno-Enisei watershed junction in accordance with modern ideas about its extent.

Pallas and his description, the Amur-Leno-Enisei river basin confluence in the area of Chita was already known in the 18th century.

At the time of the publication of the first article by T. U. Zhalsarain in 1977,[11] the area under consideration was not a "terra incognita" and a "white spot" on topographic maps, since it is located near the regional center and air routes pass over it.

[12] There was no need to discover the confluence of the Amur, Lena and Yenisey basins, it was already shown in 1967 on the map "River network density" in the "Atlas of Transbaikalia" on the terrain between Chita and Lake Arakhlei.

After several attempts, the mountain was "discovered" on the terrain by the local historian A.A. Shipitsyn and others — members of the Zabaykalsky branch of the Geographical Society of the USSR.

Rudenko, who actively participated in the search of the crossing, on July 14, 1983 by the Resolution of the Chita Oblast Committee ¹ 353 "On the recognition of state natural monuments on the territory of the Chita region"[3] the official name of the complex natural monument "Watershed Mountain on the Yablonoi Mountains"[3] was approved.

The name "Pallas Mountain" was proposed by A.A. Shipitsyn, a local historian, a member of the Zabaikalsky branch of the Geographical Society of the USSR, on October 19, 1986 in the article "A drop in the sea" published by him in the newspaper "Komsomolets Zabaikalya".

A. Shipitsyn suggested the name of the mountain only on his own initiative and without the influence of any "Community of Germans of the Zabaikalsky region".

In the manuscript of Y. T. Rudenko's reply to the magazine "Zabaikalye" there is a statement that the decision on the name "Pallas Mountain" was made by the Zabaykaksky branch of the Russian Geographical Society in 1986, that is, immediately after the publication of A.A. Shipitsyn's article.

[16] In 2008, the so-called "Scientific Council of the Museum of the Great World Watershed and the Velikiy Istok" and the head of this "museum" K. Shlyamov[17] proposed to name the mountain (in the article — "place" and the point of planetary division of fresh water) "the Velikiy Istok", and the names of T. U. Zhalsarain and P. S. Pallas "some unnamed mountains near the point of planetary division of fresh water".

Y. T. Rudenko was known to the Transbaikal people as a very active popularizer of T. U. Zhalsarain's legacy on excursions to Pallas Mountain, in classes with students and in radio programs.

In March 2019, members of ZRO SBI "Russian Geographical Society" created a separate article on Wikipedia about T. U. Zhalsarain.

In 2020 the daughter of T. U. Zhalsarain — N. A. Atutova published a book "An unadventurous story of a discovery" about her father and his legacy.
