About The Cover

The southwestern shore of Lake Nyos in Cameroon after the toxic gas disaster in August 1986 which killed an estimated 1700 people and several thousand livestock. A fountain of water created by the release of an estimated 1.0 cubic kilometer of gas washed over an 80-meter rock promontory causing a 90-centimeter drop in the lake's water level. See page 169.
