1. Ice House Memorial Marker
Today a memorial stands at the site of the original Ice House. During World War II, nuclear components of the Trinity device (a prototype nuclear weapon) were assembled here to be detonated later at Trinity Site 255 miles south near Socorro, New Mexico. During the Manhattan Project, the technical area laboratories bordered the south side of Ashley Pond. These buildings were removed by the mid-1960s. The post-war laboratory was built at its current location on the mesas south of here.
Note: The adjacent boulder memorial plaque for Manhattan Project workers dedicated in 1995 commemorates the 50th anniversary of the end of World War II.
