The north side of the taconite island in the Hill-Annex pit is shown before blasting. An adit in the bottom left side of the island is visible. The Hill-Annex Mine was an open pit iron mine in the Mesabi Range, Minnesota. The Mine started shipping ore in 1914 under Inter-State Iron Company and operated until 1978, producing some 63 million tons of ore. After the Hill-Annex was closed the pit flooded, and the site became a state park in 1988.
