Geosites
The Releng thermal spring is in a picturesque valley within an undulating landscape characterized by a deeply incised river valley; a thermal spring at temperatures of about 40℃.
This geosite features 10 km long trachytic columnar jointing escarpment rising up to 60 meters above the adjacent plains characterized by a distinctive zigzag pattern
The site is located on a river cutting where the tufa layer, approximately 5 meters thick, is exposed.
The site located between Lake Baringo and the Kamasia ranges to the west is characterized by finely layered sandstones and siltstones of the Chemeron formation of Pleistocene age.
This geosite is not defined by a fixed physical locality but is instead an interpretive observation point from which the Baringo–Bogoria halfgraben, as viewed from the Tugen Hills, can be systematically examined.
