This last comment is interesting. PFE workmen used a long steel bar to kind of stir the ice and allow it to compact itself; this was called "barring" the ice. Tamping sounds more risky to the bunker lining and bottom. The PFE ice deck directions explained that "barring" was primarily to minimize any sizable voids in the ice load.
