Resumen
The Desierto de la Tatacoa (the Tatacoa Desert), an extensive badland area related to dry climatic conditions due to a mountain barrier, lies on the eastern shore of the Magdalena River, 30 km north of Neiva, the capital of the Department (State) of Huila. It has been carved on the sub-horizontal strata of the Miocene La Victoria, Villavieja, and Gigante Formations, locally covered by Quaternary deposits. Detailed stratigraphic descriptions are available due to the presence of abundant vertebrate fossils in some of the layers. The present landscape offers a variety of landforms as badlands, pinnacles, and isolated erosional remnants forming curious figures produced by surface erosion and the different lithologies affected by the processes. © Springer International Publishing Switzerland 2016.
