Instead of forming mountains, some eruptions of lava form high, level areas called lava plateaus. First, lava flows out of several long cracks in an area. The thin, runny lava travels out of several long cracks in an area. The thin, runny lava travels far before cooling and solidifying. Again and again, floods of lava on top of earlier floods. After million of years, these layers of lava can form high plateaus. An example is the Columbia Plateau, which cover parts of Washington, Oregon, and Idaho.
