Today a memorial stands at the site of the Ranch School Ice House. During WWII, the nuclear core of the “Gadget” (the prototype atomic bomb) was assembled here and then transported to Trinity Site, 220 miles south near Socorro, NM. It was successfully detonated on July 16, 1945. During the Manhattan Project and for twenty years after, the technical area laboratories surrounded Ashley Pond. The buildings were removed by the mid-60s.
