Plateau

Highland area, usually of relatively flat terrain

In geology and physical geography, a plateau (French: [plato]; pl.: plateaus or plateaux), also called a high plain or a tableland, is an area of highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep escarpments or hills. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers.
