The Magdalena Ridge Observatory Interferometer (MROI) consists of a number of large optical telescopes placed in a pattern similar to the VLA and will beam all of the light from the telescopes into a collector interferometer building six hundred feet long. From there it will enter a controls building to be viewed. The project includes the telescope bases, the interferometer building and the controls building, all on top of Magdalena Ridge, (elevation 10,500 feet).
