Trinity Site - October 6, 2012

September 13, 2012 Posted by: Tara Cuvelier

WNPA at Trinity

On Saturday, October 6, 2012, WNPA will be out of the visitor center and out in the field!  Yes, it's time once again for us to go to the Trinity Site, set up our booth, and serve visitors as they explore the location where the world's first atomic bomb was detonated. 

Why is this such an exciting event for us?  White Sands Missile Range opens the Trinity Site to the public only twice a year--on the first Saturday of April and October.  This gives us a unique opportunity to interact with the public and represent both the WNPA and White Sands National Monument. By working side-by-side with National Park Service staff, we are able to connect people to their national parks.

    Hi Ona, The White Sands Missile Range opens the site to visitors on the first Saturday in April. It used to be in April and October but they discontinued the October day until further notice. So for 2014, the date will be April 5. You can contact the Alamogordo Chamber of Commerce at (575) 437-6120 or the Missile Range's Public Affairs office at (575) 678-1134 for more information.

Photo of animal tracks

Most desert animals are nocturnal, coming out to feed only at night when temperatures are cooler. Every animal in the white sands makes tracks on the dunes as it moves, leaving clues to its nocturnal activities.
