Caption from Torch: "The MMT facility high atop Mt. Hopkins now sports a new outer skin of metal siding, with the last portion of the installation completed by Smithsonian personnel in June. During May, the concrete floors of the building were poured. The next major milestone in construction of the joint SAO-University of Arizona project will be installation of the optical support system this summer. The MMT concept is apparently becoming the wave of the future in large telescope design. In April, the Kitt Peak National Observatory announced that work had begun on studies for a 25-meter (1,000-inch) version of the pioneering Smithsonian-Arizona telescope."
