Where We Are
Oserian Wildlife Sanctuary is located in the central part of the Great Rift Valley in Kenya, west of the Aberdare ranges and north east of the Mau escarpment. It borders both Lake Naivasha and Lake Oloidien - the highest lakes along the floor of the rift Valley. The topography of the land comprises the elevated Maela ridge that raises 7,748 ft above sea level to the lower plains on the East that stretch to the shores of the Lakes Oloidien and Naivasha at 6,200fts above sea level.
The Great Rift Valley is a vast geographical and geological feature, approximately 6,000 kilometers (3,700 miles) in length, which runs from northern Syria to central Mozambique. The rift valley varies in width from thirty to one hundred kilometers, and in depth from a few hundred to several thousand meters. It was named by the British explorer and geologist John Walter Gregory.
This massive geological split runs through the heart of East Africa and the Kenyan section of the Rift Valley is home to eight lakes. Lakes Turkana, Logipi, Bogoria, Nakuru, Elementaita and Magadi are all alkaline and are famous for the large flocks of Flamingos that feed on crustaceans. The only freshwater lakes are Baringo and Naivasha.
