Mount Longonot is a stratovolcano located southeast of Lake Naivasha in the Great Rift Valley of Kenya, Africa. It is thought to have last erupted in the 1860s. Its name is derived from the Maasai word oloonong'ot, meaning "mountains of many spurs" or "steep ridges".
Mount Longonot is protected by Kenya Wildlife Service as part of Mount Longonot National Park. A 3.1 km trail runs from the park entrance up to the crater rim, and continues in a 7.2 km loop encircling the crater. The whole tour (gate-around the rim-gate) of 13.5 km takes about 4–5 hours allowing for necessary rest breaks - parts of the trail are heavily eroded and very steep. The gate is around 2150 m asl and the peak at 2780 m asl but following the jagged rim involves substantially more than the 630 m vertical difference.
A forest of small trees covers the crater floor, and small steam vents are found spaced around the walls of the crater. The mountain is home to various species of wildlife, notably plains zebra and giraffe and buffaloes (droppings on the rim) and hartebeest. African leopards have also been reported but are extremely difficult to spot.
Mount Longonot is 60 kilometres northwest of Nairobi and may be reached from there by a tarmac road. The road was re-done by the EU and is now excellent, reducing travel time from Nairobi to around an hour. A nearby town is also named Longonot. The Longonot satellite earth station is located south of the mountain.
On March 21, 2009 Brush Fires burned up the side of the mountain and descended into the crater, trapping wildlife and feeding on drought ravaged brush.[2]
Longonot is a stratovolcano which contains a large 8 x 12 km caldera formed by vast eruptions of trachytic lava some 21,000 years ago. The current summit cone was developed within the earlier caldera. This cone itself is capped by an 1.8 km crater. Satellite cones and effusive lava eruptions occur on the flanks and within the caldera floor.[1] Periodic geodetic activity recorded at Longonot in 2004–2006 demonstrated the presence of active magmatic systems beneath this volcano.[3] It is situated in a rural area.
