It might seem impossible, but one of the most important forces of nature changing the landscape in the Turkana Basin is water. The Turkana Basin environment is arid, but even today water moves sediments around, shaping the geology of the area. Many wet and dry cycles have impacted the Turkana Basin – both on annual and millennial scales. Water impacts life around the basin, but also the ground that this life inhabits. Water movement is key to understanding geological processes. Geologists observe such processes in the present to understand the past.
Prof. Feibel took the TBI students out into the field to observe modern water processes and their impact on the land. The first stop was a hike along the Tulu Bor river and delta. Since we are in the basin during the dry season, most rivers are now dry and easy to walk along. They are perfect examples of what sediments look like when they are shaped by flowing water. Before the hike, Prof. Feibel showed the students a map of the area so that they could see the course of the river and its outlet into the delta.
