The elongated Ol Kokwe Island in the center of Lake Baringo SW of Korosi volcano consists of young basaltic scoria cones that cap a trachytic shield volcano. The volcano is the smallest in the northern part of the Kenya rift valley. N-S-trending faults cut the complex, producing west-facing scarps. Smaller islands to the north and south are faulted basaltic lava flows; Parmalok Island to the SW is a breached trachytic tuff cone that fed a small lava flow. The latest eruptive activity at Ol Kokwe was estimated to have occurred within the past thousand years (Smith 1991, pers. comm.). Hot springs, boiling mud pools, and fumaroles are present along the faults on the NE peninsula of the island and are frequently visited by tourists.

The Global Volcanism Program is not aware of any Holocene eruptions from Ol Kokwe. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Ol Kokwe page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Ol Kokwe Island in Lake Baringo is seen in an aerial view looking west towards the Saimo escarpment of the rift margin. The lake is permanently brown due to suspended sediment. The elongated Ol Kokwe Island consists of young basaltic scoria cones that cap a trachytic shield volcano. N-S-trending faults cut the island, forming the double-tipped peninsula in the foreground and the narrow peninsula at the left center. The smaller island beyond Ol Kokwe is Parmalok, a tuff cone that fed a small lava flow.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
