Well before Corey Arnold ever thought about photography, he fished.

In English, its most commonly used name means “Battleship Island” and, viewed from a certain angle offshore, its silhouette is uncannily dreadnought in nature. It was a mining facility until 1974, when it was abandoned to the elements, before partially reopening as a tourist attraction in 2009. Photo: A decades-old television. (Photo by Mark C. O'Flaherty)
