July 16 is a significant date in New Mexico history, for at the Trinity Site in White Sands, the first atomic bomb was tested at 5:29:45 am 'Mountain War Time ' (July 16, 1945), leading the world into the atomic age.
The 51,500-acre area was made a national historic landmark in 1975. [White Sands National Monument.]
The heat of the blast vaporized the steel tower and melted the desert sand, transforming it into the green glassy substance called Trinitite, which can still be seen in the area. Trinitite photo above by Mary Saxton Griffin, Fine Arts Photographer.
