the dissolution of the Soviet Union and beginning of privatization, many large plants and factories, such as the Krasnoyarsk Aluminum Plant, became owned by alleged criminal authorities and oligarchs, while others were declared bankrupt. The economic transition resulted in a dramatic rise in unemployment and numerous strikes. The best known financial scandal of the second half of the 1990s happened when ownership of the Krasnoyarsk Aluminum Plant by a known Krasnoyarsk businessman Anatoliy Bykov had been canceled after he was accused of murdering his partner, Vilor Struganov. The accusation eventually turned out to be false. The Krasnoyarsk plant's ownership problems continue through the early 21st century since nearly all of them are owned either by monopolistic financial groups or by oligarchs. Since the election of Pyotr Pimashkov as the mayor of Krasnoyarsk in 1996, the appearance of the city gradually improved: the old historical buildings were restored, the asphalt walkways were replaced with paving-stone, and numerous squares and recreation areas with fountains were either restored or constructed from scratch. Now the majority of the city keeps only a few traces of its former, drab, post-collapse look. Geography The total area of the city, including suburbs and the river, is . The river Yenisei flows from west to east through the city. Due to the Krasnoyarsk hydroelectric dam upstream, the Yenisei never freezes in winter and never exceeds in summer through the city. Near the city center, its elevation is above sea level. There are several islands in the river, the largest of which are Tatyshev and Otdyha Isles, used mainly for recreation. To the south and west, Krasnoyarsk is surrounded by forested mountains averaging in height above river level. The most prominent of them are Nikolayevskaya Sopka (notable for its ski jumping tracks), Karaulnaya Gora, and Chornaya Sopka, the latter being an extinct volcano. The gigantic rock cliffs of the Stolby Nature Reserve rise from the mountains of the southern bank of the Yenisei, the western hills from the Gremyachaya Griva crest extending westwards up to the Sobakina River, the north is generally plain, except for the Drokinskaya Sopka hill, with forests to the northwest and agricultural fields to the north and east. The major rivers in and near Krasnoyarsk are the Yenisei, Mana, Bazaikha, and Kacha Rivers, the latter flowing throughout the historical center of the city. Due to the nature of the terrain, a few natural lakes exist
