Project Chariot was a 1958 U.S. Atomic Energy Commission proposal to construct an artificial harbor at Cape Thompson on the Chukchi Sea by burying and detonating a series of nuclear devices. Although the detonation never occurred, the site was radioactively contaminated by an experiment to estimate the effect of radioactive debris on water sources. Radioactive material from a 1962 nuclear explosion at the Nevada Test Site was transported to the Chariot site in August 1962, then used in several experiments and buried. Thirty years later, the disposal was discovered in archival documents by a University of Alaska researcher. Read more here and here.
