8-year-old Josiah Fidel, of Albuquerque, plays in the dirt next to the obelisk commemorating the first atomic bomb test at the Trinity Site as other visitors to the site take photographs. The White Sands Missile Range opened the Trinity Site to the public for an open house commemorating the 70th anniversary of the first atomic test which took place there on July 16th, 1945. Several thousand visitors came to see the site, take photographs and learn more about the event. While the mood at the site seemed celebratory, at the Missile Range&#39;s two entrances leading to the site small groups of protestors gathered to raise awareness of the health impact of the test which they say has lead to a marked increase of cancer in the communities that bordered the Trinity area.
