The abrupt scarp forming the eastern boundary of the Sabana de Bogotá in Colombia appears to be of considerable geologic significance. Detailed mapping up the face of Monserrate, immediately east of the city of Bogotá, discloses the fact that Cretaceous rocks overlie probable Tertiary beds, with a crushed zone of some 15 meters in thickness at the contact. It is the opinion of the writer that the scarp is the direct result of overthrusting, with differential erosion having played some part in its further development. The feature is here named the Monserrate-Guadalupe scarp, and the overthrust, the Bogotá fault.
