Cinder cone, Kenya. (A) Cinder cones consist of pyroclastic material that has settled out in a cone near a volcanic vent. The larger, heavier material settles close, and the smaller, lighter material settles farther away. (B) The southern end of Lake Turkana in Kenya has several cinder cones. This one is 1 km (0.6 mi) in diameter, 220 m (700 ft) tall, and has a 187 m (600 ft) deep crater.
