Steelworkers Build the 300-foot

In April 1961, the Bristol Steel and Iron Works, Inc. was awarded the contract to build the 300-foot telescope in Green Bank., West Virginia. Here, four steelworkers bolt the corners of the square base that will hold the 300-foot dish.

The 300-foot’s warped surface

In 1966, after years of snow and workmen’s trampling, the aluminum surface of the 300-foot telescope in Green Bank, West Virginia became warped. A new surface was installed in 1970.
