The location of a nuclear disposal site in Pennsylvania is unknown, as topographic maps from 2014 redacted its whereabouts, showing only that it was located somewhere in the state. Later maps from 2015 on the U.S. Department of Energy's website still did not specify the exact location, instead noting it as the "Pennsylvania Disposal Site-PA 43" without providing further geographic details.
