The trachytic Longonot stratovolcano SE of Lake Naivasha contains an 8 x 12 km caldera. A large central cone, seen here from the SW, was constructed within the caldera and forms the summit of the volcano. It is truncated by a circular, 1.8-km-wide caldera. Post-caldera lavas erupted onto its floor give it a flat surface. Masai tradition records a lava flow on the northern flank during the 19th century. Similarly youthful-looking lava flows occur on the SW flank.
