Trinity Site is where the first atomic bomb was tested at 5:29:45 a.m. Mountain War Time on July 16, 1945. The 19-kiloton explosion not only led to a quick end to the war in the Pacific but also ushered the world into the atomic age. All life on Earth has been touched by the event which took place here.

The 51,500-acre area was declared a national historic landmark in 1975. The landmark includes base camp, where the scientists and support group lived, ground zero, where the bomb was placed for the explosion, and the McDonald ranch house, where the plutonium core to the bomb was assembled. Visitors to a Trinity Site Open House see ground zero and the McDonald ranch house. In addition, one of the old instrumentation bunkers is visible beside the road just west of ground zero

Schmidt/McDonald Ranch House: The Schmidt/McDonald Ranch House is part of the National Historic Landmark and is where the Plutonium core of the bomb was assembled. It is located two miles southeast of Ground Zero. In 1984, the Schmidt/McDonald Ranch House was restored to its 1945 condition through the coordination effort of the U.S. Army Department of Visitors wishing to include the ranch house in their tour.
