Lake Nyos-Killer Lake - Cameroon

The real name of this place is Lake Nyos but the locals now call it “Killer Lake” or “The Lake that Killed” - a well deserved name.  Located in a crater on the flanks of an inactive volcano the extremely deep waters lie above a pool of magma that slowly leaks carbon dioxide. It’s part of the Oku volcanic configuration and is located in the north-west region of Cameroon. In 1986 a vast bubble of carbon dioxide mixed with sulfur and hydrogen spewed to the surface.  In total, 1.6 million tonnes of this lethal gas spread over a huge area - reaching 23 kilometers away from the source. Hugging the ground this deadly and near undetectable concoction swept over villages and small towns.  Approximately 1,700 people and 3,500 farm animals were killed within two hours.  Survivors experienced long-term side effects including lesions, soft-tissue burns and respiratory illnesses.
Lake Nyos - otherwise known as "The Lake that Killed." The outgassing of carbon dioxide was so large that it lowered the level of the lake by over a metre and turned the water to the colour of blood. 1,700 people died within two hours.

Lake Baikal – Siberia, Russia--the deepest lake in the world

Lake Baikal is in Southern Siberia in Russia, located between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast, near the city of Irkutsk. It is also known as the "Blue Eye of Siberia". It contains more water than all the North American Great Lakes combined.
At 1,637 meters (5,371 ft), Lake Baikal is the deepest lake in the world,[3] and the largest freshwater lake in the world by volume.[4] However, Lake Baikal contains less than one third the amount of water as the Caspian Sea which is the largest lake in the world.
Situated in south-east Siberia, the 3.15-million-ha Lake Baikal is the oldest (25 million years) and deepest (1,700 m) lake in the world. It contains 20% of the world's total unfrozen freshwater reserve. Known as the 'Galapagos of Russia', its age and isolation have produced one of the world's richest and most unusual freshwater faunas, which is of exceptional value to evolutionary science.

Baikal-World's Deepest Lake(Siberia, Russia)

Lake Baikal in southern Russia is the world's deepest lake. It is 5314 feet deep (1637 meters) and it's bottom is at 4215 feet (1285 meters) below sea level. This large lake is located in an active continental rift zone which is estimated to be widening at a rate of about 1 inch (2.5 centimeters) per year.The Baikal Range that fits Lake Baikal from the North-West, is the realm of mountains and taiga. The central part of the range is an unexpected hard-to-get-to land full of contrast and surprises, visited only by hunters, tourists and research expeditions. The highest point of the Baikal Range is the Cherskiy mountain (2588 m), the first ascent of which was made only in 1975. The start point of the route is the city of Severobaikalsk, which is accessible via Transsiberian Railroad and BAM ("Baikalo-Amurskaya Magistral", Baikal-Amur Railroad).
