Ol Kokwe

Shield volcano · Kenya · 1130m

Ol Kokwe Island in Lake Baringo is seen in an aerial view looking W towards the Saimo escarpment of the rift margin. The elongated 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.

Geological summary

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. N-S-trending faults cut the complex, producing W-facing scarps. Smaller islands to the N and S 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 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.
