Mount Longonot

Mount Longonot rises within Kenya's Great Rift Valley, southeast of Lake Naivasha, reaching an elevation of about 2,776 meters. It is a dormant stratovolcano built from trachytic lava flows, with a large, largely intact summit caldera formed by an eruption and subsequent collapse, its inner walls now covered in dense forest and its floor marked by numerous smaller fumarolic vents. The volcano's last significant eruption is estimated to have occurred around 1863, based on early written accounts, though the exact date remains unconfirmed, and it has shown no eruptive activity since. Mount Longonot and its caldera are protected within Mount Longonot National Park, a popular hiking destination affording views across the surrounding rift floor. This entity documents Mount Longonot specifically as a geological formation, a dormant Rift Valley stratovolcano with a large, forested summit caldera.
