DescriptionThe old harbor piers with a catwalk and light on the southern wall. This image was featured as History Mystery #40 with the question "The old piers (see the remnants at the Oval Beach) were completed in 1873 and remained in use until about 1909. What is unusual in this photo and how was this circa 1897 photo dated?" and the solution "In 1894, a catwalk was installed so that the light - mounted on cart that rolled on steel rails - could be serviced without going to the pier head. The system was removed in 1900."
