Killbuck Island

Killbuck Island, also known historically as Smoky Island or Nelson Island, was a former island in the Ohio River at its confluence with the Allegheny River, near the Point in present-day Pittsburgh, Pennsylvania. The island was associated with the Delaware chief Gelelemend, known to English speakers as John Killbuck Jr., and was the site of the Tradesmen's Industrial Exposition in the late 19th century before disappearing due to flooding and land alteration.
