History
It was founded in 1923[2] as Nezametny (Незаме́тный), after discovery of rich gold deposits. It was granted town status and renamed in 1939.[citation needed] During World War II, an airfield was built here for the Alaska-Siberian (ALSIB) air route used to ferry American Lend-Lease aircraft to the Eastern Front.[9]
Administrative and municipal status
Within the framework of administrative divisions, Aldan serves as the administrative center of Aldansky District.[1] As an inhabited locality, Aldan is classified as a town under district jurisdiction.[1] As an administrative division, it is, together with two rural localities, incorporated within Aldansky District as the Town of Aldan.[1] As a municipal division, the Town of Aldan is incorporated within Aldansky Municipal District as Aldan Urban Settlement.[5]
Economy
Aldan remains a productive gold and mica mining center, largely avoiding the large drop in population suffered by most other towns in the Russian Far East in the years after the dissolution of the Soviet Union.
Transportation
The town stands on the A360 Lena Highway, which connects Yakutsk and Never, as well as on the Amur–Yakutsk Mainline railway. It is served by the Aldan Airport.
Climate
Aldan has the typical eastern Siberian subarctic climate (Köppen Dfc) with short, warm, and humid summers with cool nights, and severely cold winters. though it is affected by the Pacific Ocean more than localities in the lower Lena basin, which gives it much heavier rainfall during the summer than most of the republic, as well as a little more snowfall and rather less extreme winter temperatures – though still extremely cold for the latitude and as much as 10 °C or 18 °F colder than settlements actually on the Okhotsk coast. In spite of the less extreme winters vis-à-vis more northerly parts of Sakha, Aldan has never seen any day above freezing from 22 November to 7 March inclusive.[when?] Although winters are somewhat less extreme than Yakutsk, summers are actually somewhat cooler, and cloudier, than those northerly areas.
The coldest temperature recorded in Aldan since the weather station was opened in 1937 has been −50.0 °C or −58.0 °F on 20 January 2023 and the hottest 36.5 °C or 97.7 °F on 3 July 2021. February 1969, with a mean temperature of −33.6 °C or −28.5 °F, has been the coldest month on record, shading the preceding January which averaged −33.4 °C or −28.1 °F. The hottest month has been July 1941 which averaged 20.7 °C or 69.3 °F, the wettest August 2006 with 269 millimetres or 10.59 inches of rain, and the driest March 1937 with only 2 millimetres or 0.08 inches of water equivalent.
