History and name of the Lake
Lake Tanganyika is an ancient lake, estimated to be over 400,000 years old, and is considered one of the world’s oldest lakes. The name “Tanganyika” is derived from the Swahili words “tanganika” and “tanganikwa,” meaning “sail in the wilderness” or “long lake.” The lake was known by Arab and Indian traders as early as the 9th century, but it was not well explored by Europeans until the late 19th century.
Lake Tanganyika is a long, narrow lake, stretching about 400 miles from north to south and averaging about 50 miles in width. The lake is over 4,000 feet deep in some places, making it the second deepest lake in the world after Lake Baikal in Russia. The lake is surrounded by mountainous terrain, with several active and inactive volcanoes in the region. The lake has several large inlets and outlets, including the Lukuga River, which drains the lake. The lake is also fed by numerous smaller rivers and streams.
Lake Tanganyika is a Rift Valley lake, formed as a result of tectonic activity that caused the Earth’s crust to pull apart and form a depression. The lake is fed by underground springs and rivers, and its water is known for its high clarity and low mineral content. The lake’s bottom is composed of sedimentary rock and is rich in fossil deposits, including the remains of ancient mollusks, crustaceans, and other organisms. The lake is surrounded by young volcanic mountains and there are several active and inactive volcanoes in the region, which have played a role in shaping the lake’s geography and ecology over time.
