One of Africa's most notable volcanoes, Nyiragongo contained a lava lake in its deep summit crater that was active for half a century before draining suddenly in 1977. This July 23, 1982 photo from the south crater rim shows a small active lava lake surrounded by black lava flows from the new June 1982 lava lake. Narrow benches halfway up the steep-walled, 1.2-km-wide summit crater mark former lava lake levels.
