Organized by Frederick Belton As a result of the recent explosive eruption, the future of Ol Doinyo Lengai is very uncertain at this time. It is not known if there will be further explosive activity or if flows of fluid lava will resume at any time in the near future. Until further notice we will not offer any expeditions. We hope that Lengai will again resume its more or less continuous activity as before. However, if the history of the 1966-1967 eruption repeats itself, many years may pass before easily accessible natrocarbonatite lava again flows at Lengai. Should any individuals or groups be interested in a guided visit to Lengai, we would consider organizing a custom expedition by request. Please visit the OL DOINYO LENGAI WEBSITE. If you have questions about Ol Doinyo Lengai or would like to report your observations from a Lengai visit, please SEND AN EMAIL.
