Freediving the century-plus-old ruins of Duluth’s outer harbor. First the old breakwater wall (cribbing filled with rocks) that stretches 1000′ from the Vietnam Memorial to the red buoy. The buoy’s function is to mark this as a shipping hazard (at that distance from shore the buoy is in 30 feet of water). The destruction of the breakwater wall in a storm spurred the digging of the canal. Then the column or pillar of Uncle Harvey’s Mausoleum, essentially a bundle of timbers sheathed in concrete. Then Uncle Harvey’s itself, in 16 feet of water, also built on cribbing.
