78. Holy Loch. (NS 163 806)

For thirty years, between 1961 and 1991, the Holy Loch was the location of a base for the U.S. Navy's 14th Submarine Squadron. It was handed back to the MoD in June 1992. During its time as an American base, a vast amount of waste, some of it toxic, was dumped into the loch, and which was left on the seabed when the Americans departed.
