TBI Cliffs

|TBI Cliffs

Students learned the concept of superposition, where the oldest sediment or rock layers are on the bottom of an exposed outcrop. However, due to various forces, such as movement of the plates that make up the Earth’s crust, or changes in water bodies, the relative position of rock layers can change. Understanding geology is important in dating fossils and determining the dynamics of landscapes.

Dr Chris Lepre is explaining today’s exercise.

Alexa and Chris are measuring the height and composition of the exposed layers of sediment.

Hello, I am Anja Deppe. I am a physical anthropologist and am interested in all aspects of ecology and animal behavior. In Madagascar, I investigated how mouse lemurs (tiny primates) use their senses of seeing, hearing, and smelling to avoid predators. I am currently the director of the Turkana Basin Institute Field School and share my time between Kenya and Stony Brook University.
