Kitt Peak National Observatory
With 23 telescopes, Kitt Peak National Observatory is the largest, most diverse gathering of astronomical instruments in the world. This is a closer view of a small portion of the total complex.
Kitt Peak was selected in 1958 as the site from a survey that included more than 150 mountain ranges across the United States. Located on lands of the Tohono O’odham Nation in the Sonoran Desert southwest of Tucson, Arizona, Kitt Peak is home to the world’s largest collection of optical telescopes under desert skies.
The weather on this day at the peak (6,880) was a cool 35 degrees. The storm clouds overhead is an approaching snow squall coming over the mountain.
