EL PASO, Texas (KTSM) — After a pause in activities due to the pandemic, White Sands Missile Range is opening Trinity Site, where the first atomic bomb was tested in 1945, to the public in October.

No reservations are required for the free open house, which will be on Oct. 2. Visitors will be able to take a quarter-mile walk to ground zero, where a small obelisk marks the spot where the bomb was detonated at 5:29:45 a.m. on July 16, 1945. Visitors will also be able to ride a shuttle that will take them from ground zero to Schmidt/McDonald Ranch House, where scientists assembled the plutonium core of the bomb.

Visitors will also be able to experience what life was like for a ranch family in the early 1940s.
