Russia encompasses 17,098,242 square kilometers, making it the largest country by land area on Earth. The territory extends 9,000 kilometers from Kaliningrad Oblast on the Baltic Sea to the Bering Strait, which separates Russia from Alaska by 82 kilometers of water. The north-south span reaches 4,000 kilometers from Franz Josef Land in the Arctic Ocean to the Caucasus Mountains on the border with Georgia and Azerbaijan. This landmass crosses eleven time zones and occupies portions of both Eastern Europe and Northern Asia, representing approximately one-eighth of Earth's inhabited land area.
The Ural Mountains form the traditional boundary between European Russia and Asian Russia, running north-south for approximately 2,500 kilometers from the Kara Sea coast to the Ural River near the border with Kazakhstan. Mount Narodnaya stands as the highest point in the Urals at 1,895 meters above sea level. The range formed between 250 and 300 million years ago during the Uralian orogeny, when the supercontinent Pangaea was assembling. Erosion has reduced these ancient mountains to modest elevations compared to younger ranges. The Urals contain significant mineral deposits including iron ore, copper, nickel, chromite, platinum, and gold, which have supported industrial development since the 18th century. Major cities along the Urals include Yekaterinburg, with a population exceeding 1.5 million, and Chelyabinsk, which serves as a metallurgical center. The Middle Urals, where these cities are located, represent the lowest and most eroded section of the range, with peaks rarely exceeding 600 meters.
The Caucasus Mountains extend approximately 1,200 kilometers between the Black Sea and the Caspian Sea along Russia's southern border with Georgia and Azerbaijan. This range divides into the Greater Caucasus in the north and the Lesser Caucasus in the south, with the international boundary following the crest of the Greater Caucasus. Mount Elbrus, located in the Kabardino-Balkarian Republic of Russia, reaches 5,642 meters, making it the highest mountain in Europe by the geographic definition that places the continental boundary along the Caucasus watershed. Elbrus is a dormant stratovolcano with twin summits, the western peak rising 21 meters higher than the eastern. The first documented ascent of the eastern summit occurred in 1829 by Khillar Khachirov, a Circassian guide accompanying a Russian military expedition. The Caucasus formed approximately 25 million years ago during the Alpine orogeny as the Arabian Plate collided with the Eurasian Plate, a process that continues today at a rate of several centimeters per year. The range experiences significant seismic activity, including the 1988 Spitak earthquake in Armenia that measured 6.8 on the Richter scale. The North Caucasus Federal District contains multiple autonomous republics including Dagestan, Chechnya, Ingushetia, North Ossetia-Alania, Kabardino-Balkaria, and Karachay-Cherkessia, each with distinct ethnic populations and languages.
Lake Baikal occupies a rift valley in southern Siberia, holding 23,615.39 cubic kilometers of water, which represents approximately 22 to 23 percent of Earth's surface freshwater. The lake extends 636 kilometers in length with a maximum width of 79 kilometers. The maximum depth reaches 1,642 meters, making Baikal the deepest lake on Earth. The lake floor lies 1,186 meters below sea level in its deepest sections. Baikal formed between 25 and 30 million years ago, making it the oldest lake on Earth. The rift continues to widen at approximately 2 centimeters per year. Over 300 rivers and streams flow into Baikal, with the Selenga River contributing approximately half of the total inflow. The Angara River provides the sole outflow, eventually joining the Yenisei River system. Water residence time in Baikal averages 330 years. The lake contains 1,700 species of plants and animals, with approximately two-thirds found nowhere else on Earth. The Baikal seal (nerpa) represents the only exclusively freshwater seal species, with a population estimated between 80,000 and 100,000 individuals. Scientific theories regarding seal arrival include migration from the Arctic Ocean via river systems during previous glacial periods. UNESCO designated Lake Baikal a World Heritage Site in 1996, recognizing an area of 88,000 square kilometers including the lake and surrounding territory. Winter ice on Baikal reaches thicknesses of 1 to 2 meters, supporting vehicle traffic from January through May. Ice coverage typically begins in January and breaks up in May, though exact timing varies by location and weather patterns.
The Volga River flows 3,530 kilometers from the Valdai Hills northwest of Moscow to the Caspian Sea, making it the longest river in Europe. The drainage basin covers 1,360,000 square kilometers, approximately one-third of European Russia's total area. The river passes through or borders 15 Russian regions and four of the country's 20 largest cities. The Volga begins at an elevation of 228 meters near the village of Volgoverkhove in Tver Oblast. Approximately 200 tributaries feed the river, with the Kama River contributing the largest volume of water. Discharge at the mouth averages 8,060 cubic meters per second. A system of reservoirs created by eight hydroelectric dams regulates flow along much of the river's length. The Rybinsk Reservoir, completed in 1941, covers 4,580 square kilometers. The Volga-Baltic Waterway, opened in 1964, connects the river to the Baltic Sea through a series of canals and Lake Onega. The Volga-Don Canal, completed in 1952, provides a 101-kilometer connection to the Sea of Azov and Black Sea. These waterways transform the Volga into a central hub for inland shipping. The river freezes for approximately three months each year, typically from December through March, with ice thickness reaching one meter in northern sections. Commercial navigation operates from April through November in most areas. The Volga Delta where the river enters the Caspian Sea spans approximately 27,000 square kilometers, making it the largest river delta in Europe. The delta contains over 500 channels and islands, supporting populations of Caspian seals and sturgeon species including beluga (Huso huso), Russian sturgeon (Acipenser gueldenstaedtii), and stellate sturgeon (Acipenser stellatus). Astrakhan, located 60 kilometers from the Caspian Sea on the delta's main channel, serves as the primary port for the lower Volga region.
Siberia encompasses approximately 13,100,000 square kilometers, extending from the Ural Mountains eastward to the Pacific Ocean and from the Arctic Ocean southward to the borders with Kazakhstan, Mongolia, and China. This region accounts for 77 percent of Russia's territory but contains only 27 percent of the country's population, approximately 33 million people. The term Siberia derives from the Tatar language, though etymological origins remain debated among linguists. The Central Siberian Plateau occupies much of the region between the Yenisei and Lena Rivers, with elevations typically ranging from 500 to 700 meters. The Putorana Plateau in the northern portion reaches elevations exceeding 1,700 meters and contains over 25,000 lakes. Permafrost underlies approximately 65 percent of Russian territory, with continuous permafrost covering most of Siberia north of 60 degrees latitude. Permafrost depth reaches 1,500 meters in the Sakha Republic (Yakutia). Yakutsk, the capital of Sakha Republic, holds the distinction of being the largest city built on continuous permafrost, with a population exceeding 300,000. Winter temperatures in Yakutsk average minus 38.6 degrees Celsius in January, with the record low of minus 64.4 degrees Celsius recorded in February 1891. The towns of Verkhoyansk and Oymyakon compete for the designation of coldest permanently inhabited place on Earth, both having recorded temperatures below minus 67 degrees Celsius. Oymyakon recorded minus 67.7 degrees Celsius in February 1933, though some sources report an unofficial reading of minus 71.2 degrees Celsius from 1924. Summer temperatures in these locations can exceed 30 degrees Celsius, creating annual temperature ranges approaching 100 degrees Celsius.
The Kamchatka Peninsula extends approximately 1,250 kilometers southward into the Pacific Ocean from the Russian mainland, separating the Sea of Okhotsk from the Bering Sea and Pacific Ocean. The peninsula contains over 160 volcanoes, 29 of which remain active. Klyuchevskaya Sopka stands as the highest active volcano in Eurasia at 4,750 meters, though the summit elevation changes with eruptions. The volcano has erupted over 50 times since 1697, with significant eruptions occurring in 1944-1945, 1966, 1983, 2005, 2009, and 2013. UNESCO designated the Volcanoes of Kamchatka World Heritage Site in 1996, initially protecting 3.7 million hectares and expanding to 3.8 million hectares in 2001. The site includes six separate protected areas containing the most pristine volcanic regions of the peninsula. Kamchatka's location on the Pacific Ring of Fire results from the subduction of the Pacific Plate beneath the Okhotsk Plate at a rate of approximately 8 centimeters per year. The Valley of Geysers, located in the Kronotsky Nature Reserve, contains approximately 90 geysers and numerous hot springs concentrated in a 6-kilometer-long valley. This represents the second-largest concentration of geysers on Earth after Yellowstone National Park in the United States. A massive mudslide in 2007 buried approximately two-thirds of the valley, though subsequent landslide activity in 2013 reopened some of the buried geysers. Brown bears (Ursus arctos) inhabit Kamchatka in high densities, with populations estimated at 10,000 to 14,000 individuals. The South Kamchatka Sanctuary and Kuril Lake serve as crucial salmon spawning grounds, attracting bears in concentrations rarely seen elsewhere. Petropavlovsk-Kamchatsky, the peninsula's largest city with a population exceeding 180,000, ranks as one of the world's largest cities inaccessible by road from other settlements. The city connects to the rest of Russia only by air and sea transport.
The Lena River flows 4,294 kilometers from its source in the Baikal Mountains south of the Central Siberian Plateau to the Laptev Sea in the Arctic Ocean, making it the 11th longest river in the world. The drainage basin covers 2,490,000 square kilometers. The river begins at an elevation of 1,640 meters approximately 20 kilometers west of Lake Baikal. Average discharge at the mouth reaches 17,000 cubic meters per second, with peak flows during spring melt exceeding 200,000 cubic meters per second. The Lena Delta covers approximately 32,000 square kilometers, the largest delta of any river flowing into Arctic seas. The delta contains approximately 1,500 islands separated by channels and streams. Ice coverage extends from October through June in the delta region and from November through May in southern portions. The spring breakup often causes significant flooding as ice jams block flow. The Lena Pillars Nature Park, designated a UNESCO World Heritage Site in 2012, protects a 40-kilometer stretch of vertical rock formations along the river's middle course in Sakha Republic. These pillars reach heights of 100 to 200 meters above the river, formed from Cambrian limestone deposited 530 million years ago and subsequently uplifted and eroded. The Vilyuy River, a right tributary joining the Lena near the town of Sangar, extends 2,650 kilometers and drains an area exceeding 450,000 square kilometers. The Aldan River, the Lena's largest tributary by discharge, contributes an average of 5,060 cubic meters per second. Yakutsk, Siberia's oldest city, was founded on the Lena's banks in 1632 as a Cossack fort. The city serves as a major port during the navigation season, connecting river settlements with the Trans-Siberian Railway at Ust-Kut, 2,700 kilometers upstream.
The Altai Mountains occupy a region where Russia, Mongolia, China, and Kazakhstan converge, with the Russian portion located in Altai Republic and Altai Krai. Mount Belukha, the highest peak in the Altai range, reaches 4,506 meters and straddles the border between Russia and Kazakhstan in the Katun Range. The mountain features twin peaks separated by a shallow saddle, with the east summit slightly higher than the west. Glaciers cover approximately 70 square kilometers of Mount Belukha's slopes, feeding the Katun River, which flows 688 kilometers to join the Ob River. The Golden Mountains of Altai UNESCO World Heritage Site, designated in 1998, protects 1,611,457 hectares across three separate areas: Altaisky Nature Reserve, Katunsky Nature Reserve, and the Ukok Plateau. The site preserves ecosystems ranging from steppe to mixed forest to alpine vegetation, supporting populations of snow leopard (Panthera uncia), Altai argali sheep (Ovis ammon ammon), and Siberian ibex (Capra sibirica). The Ukok Plateau, located at elevations between 2,200 and 2,500 meters near the borders with Mongolia and China, gained international attention in 1993 when archaeologist Natalya Polosmak discovered the mummy of a Pazyryk culture woman dated to the 5th century BCE. The mummy, known as the Ice Maiden or Princess of Ukok, was preserved in permafrost along with six horses and elaborate grave goods including clothing with gold decorations. The Pazyryk culture, which inhabited the Altai region from approximately 600 to 200 BCE, left numerous burial mounds (kurgans) across the region. The Altai region contains over 2,000 lakes, with Lake Teletskoye reaching depths of 325 meters and extending 78 kilometers in length. The lake contains approximately 40 cubic kilometers of water, fed primarily by the Chulyshman River.
The Sayan Mountains form two ranges in southern Siberia: the Western Sayan extending approximately 650 kilometers along the border between Khakassia and Tuva, and the Eastern Sayan running roughly 1,000 kilometers from the Western Sayan to Lake Baikal. The highest peak, Munku-Sardyk, reaches 3,491 meters on the border between Russia's Buryatia Republic and Mongolia. The Sayano-Shushenskaya Dam on the Yenisei River, completed in 1985, created a reservoir extending 320 kilometers upstream. The dam stands 245 meters high, making it the largest power plant in Russia by installed capacity at 6,400 megawatts. An accident on August 17, 2009, resulted in the deaths of 75 workers when a turbine failure caused catastrophic flooding of the engine room. The Sayan region supports populations of Siberian musk deer (Moschus moschiferus), valued for musk produced by males in abdominal glands. The Ergaki Nature Park, established in 2005, protects 342,873 hectares of mountain terrain in the Western Sayan, characterized by granite peaks, mountain lakes, and taiga forest. The park contains over 100 lakes, most formed by glacial activity during the Pleistocene.
The Yenisei River extends 3,487 kilometers from the confluence of the Bolshoy (Greater) Yenisei and Maly (Lesser) Yenisei near Kyzyl in Tuva to the Kara Sea in the Arctic Ocean. Including the Selenga-Baikal-Angara system, which some geographers consider the true source, the total length reaches approximately 5,539 kilometers. The drainage basin covers 2,580,000 square kilometers. Average discharge at the mouth reaches 19,600 cubic meters per second, making it the largest river system flowing into the Arctic Ocean. The Yenisei divides Siberia into western and eastern regions, with the boundary between the West Siberian Plain and Central Siberian Plateau following the river valley. Krasnoyarsk, a city of over one million inhabitants, sits on both banks of the Yenisei approximately 3,350 kilometers from its mouth. The Krasnoyarsk Dam, completed in 1972, created a reservoir extending 388 kilometers upstream and generated controversy when construction proceeded despite warnings that the dam would disrupt indigenous fishing communities and alter the river's thermal regime. Norilsk, located on a tributary of the Yenisei, developed in the 1930s around nickel and copper mining operations. The city's population exceeds 175,000, making it the second-largest city above the Arctic Circle after Murmansk. Norilsk Nickel, the company operating the mines and smelters, produces approximately 40 percent of the world's palladium and 11 percent of its nickel. The industrial operations have resulted in severe environmental damage, with sulfur dioxide emissions exceeding 1.
