684-581: The Taz River . It is believed that the name of the Yenisei River was transmitted, either directly or indirectly, from Samoyed-speaking peoples in the region with whom the Russians had contact. This contact eventually led to the adoption of the name "Yenisei", with a Russian accent. Additionally, by the end of the 16th century, the Yenisei River was already known to Dutch navigators, who referred to it as "Gilissi", "Gelissi", or "Geniscea", among other names. Although

798-735: The Soviet government began to greatly increase effort to produce diamonds on its own territory, due in part to some other diamond-producing nations being unwilling to sell to the USSR. Expeditions were organized in the basins of the Yenisei River and in the Ural Mountains . The Ural expedition proved the more successful, finding small, but commercially viable deposits. An additional government decree signed by Stalin in 1946 announced further exploration for diamonds, with expeditions mounted from Irkutsk into

He described a nest of blue clay in the area between the Vilyuy and Malaya Bituobiya Rivers, but as kimberlites had not yet been discovered there was no official attention. Around the beginning on the 20th century, a number of scientists and geologists noted similarities between parts of the Central Siberian Plateau and areas in South Africa , where exploitation of primary diamond deposits had already begun. In 1937,

1026-632: The exact spelling varied, these are phonetically similar to "Yenisei". In particular, the modern Dutch pronunciation of "Geniscea" as [xɛnisə] is quite close to "Yenisei". The term "Yenisei" (Енисей) appeared in Russian literature slightly later, around 1600, in the form that is still used today. Unlike in Dutch, the Russian spelling has been relatively stable since the 17th century, with only minor variations such as "Yeniseya" (Енисея) or "Yenisya" (Енися). The etymology of "Yenisei" remains unclear. Renowned linguist Max Vasmer , for instance, has suggested that

1216-541: The region of the Yenisei River . The first officially recorded discovery of diamonds in Yakutia (the present-day Sakha Republic ) was made in 1949 on an expedition along the Vilyuy. Initially, discoveries centered on placer deposits , which did not uncover the enormous primary deposits in the form of kimberlite pipes. The first kimberlite deposit, Zarnitsa mine , was discovered on August 21, 1954. Further exploration in 1955 found over fifteen primary deposits, including

Success came with the steamers Frazer , Express in 1878 and, the next year, Moscow hauling supplies in and wheat out. The Dalman reached Yeniseisk in 1881. Imperial Russia placed river steamers on the massive river in an attempt to free up communication with land-locked Siberia. One, St. Nicholas took

1292-518: The river. Both the Ob and Yenisey mouths feed into very long inlets, several hundred kilometres in length, which are shallow, ice bound and prone to high winds and thus treacherous for navigation. After the completion of the railway, river traffic reduced to only local service as the Arctic route and long river proved much too indirect a route. The first recreation team to navigate the Yenisey's entire length, including its violent upper tributary in Mongolia,

Some of the earliest known evidence of Turkic origins was found in the Yenisey Valley in the form of stelae , stone monoliths and memorial tablets dating from between the seventh and ninth centuries AD, along with some documents that were found in China's Xinjiang region . The written evidence gathered from these sources tells of battles fought between
