Quaternary basalt-trachyte volcano located within the rift (Suguta Trough) in the central part of Maralal volcanic area, Turkana County, Kenya. The main volcanic edifice rises 700 m above the rift floor and covers 33 x 20 km, but extends to the north for 9 km in the form of a chain of fissure-controlled scoria cones, tuff rings and maars (Dunkley et al. 1993).

As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
