Vents of the northern part of the Olkaria volcanic complex are visible immediately S of Lake Naivasha (upper right). It comprises up to 80 individual rhyolitic centers, many of which are visible in this Landsat image. The youngest known eruption has a radiocarbon age of about 180 years. Fumarolic activity occurs at the Njorowa Gorge and at the Orengingnai and Orkaria (Olgaria) pumice cones.
