Expedition of S. Obruchev

In the northeastern part of Russia there is an extensive mountainous country, intersected by the valleys of Yana, Kolyma, Indigirka and other rivers. But these mountain ranges appeared on the map relatively recently, in the 30-40's. 19 tbsp. and then, like the fruit of the imagination of cartographers who did not see them with their own eyes. After the expedition of ID Chersky in 1891 for 35 years no one was interested in this vast territory. Only in 1926 the expedition of S. Obruchev went to Northeastern Siberia. What awaited the expedition, no one had the slightest idea.

Only in 1926 the expedition of S. Obruchev went to Northeastern Siberia

First of all, the expedition of S. Obrucheva intended to study the western part of the Indigirka basin and cross the Verkhoyansk Range. The researchers were surprised by the striking disparity between the map and the surrounding terrain, and Indigirka, struck by its wildness and numerous rapids. On both sides of the river towered high mountain peaks, the peaks of which even in the height of summer were covered with snow. None of the geographers had no idea that in North Siberia such high mountains are located.

Expedition of S. Obruchev crossed nine parallel mountain ranges. An expedition also visited the banks of the previously unknown Chibagalakh. To do this, it was necessary to overcome another 1,500 km of the road and cross countless mountain ranges. On the way back, the expedition of S. Obruchev stopped in the village of Oimyakon, located in the intermontane basin. It was only the beginning of November, but the severe cold that prevailed in Oymyakon suddenly shut down all the thermometers of the expedition. It turned out that frosts reached here -500 C, and in Verkhoyansk, which was previously considered the Pole of Cold, the average temperature was at this time -300 C. This led SV Obruchev to the idea that the real Pole of Cold is located precisely in Oimyakon.

In the years 1929-1930 S. Obrucheva's new expedition explored the basin of another large river, the Kolyma and the eastern slopes of the Chersky Range. The geographic map resulted in significant corrections. The upper course of the Kolyma, for example, "moved" more than 200 km to the southeast, and the lower, on the contrary, - to the south-west. Further to the south, the Tas-Kistabite Range, which was discovered by I.D. Chersky, was located, in this direction the eastern part of the Chersky Range also deviated.

New names appeared on the map, like the Yukagir plateau, the Alazey plateau, the Gydan range, where in 1946 they discovered vast areas of mountain glaciation, whose existence was denied by some geographers. This happened with the help of aviation, when a tall, snow-covered Suntar-Hayat Range 450 km long was discovered to the south of the Chersky Range.

Its highest mountain Mus-Khaya (2959 m) in its height among the mountains of northeast Asia is second only to Mount Pobeda (3003 m) in the range of Chersky.
