Basalt rock columns are formed when thick basalt lava masses cool slowly and contract forcing jointing or fracturing to occur which forms the columns. Many waterfalls do flow over basalt rock but not over distinct basalt rock columns. When water does flow over the rock columns it can be quite a beautiful sight to see. Here are some fine examples from around the world.

The first base is the Tejon RCS Facility owned by Northrop Grumman. 34 54'58.78" N 118 30'20.73" W The second base is the Gray Butte RCS Facility owned by McDonnell Douglas. 34 33'21.72" N 117 38'27.61" W The third base, which is confused for being Area 51, because of the underground installation, is Helendale Avionics Facility, owned by Lockheed Martin. 34 48'53.58" N 117 15'24.53" W The fourth base, which is the strangest one is known as the Anthill. It looks like a Sumerian Zigurat. The base is connected to the hill.
