Construction and framing of a computer room addition at the base of the 150-foot tower telescope, Mount Wilson Observatory. The steel framing for the walls is seen, as is the partially-completed roof. An unidentified construction worker stands within the framed building. A portion of the tower's base is seen next to the new building, at the far right. Ladders and other pieces of construction equipment are in the area.
