Beneath its translucent green waves, Canyon Ferry Lake reservoir hides the remains of the small town of Canton, Montana. Founded in the 1860s, Canton’s cemetery was perched on top of a hill high enough to escape being flooded during the construction of the Canyon Ferry Dam between 1949 and 1954.

The dam was constructed to flood the Missouri River and replace a much smaller dam built in 1898. Canyon Ferry Lake is now Montana’s third-largest lake and a popular spot for fishing and boating in the summer, as well as skating and ice-boat speed sailing in the winter.

Cemetery Island contains graves that date from the late 1800s to 2000. New burials are no longer allowed, but visitors can explore the small island, which is filled with dramatic rock formations and small beaches. Iron fences, crooked tombstones, and dramatic lake views combine for an atmosphere that would be the perfect setting for a horror film or Scooby Doo episode. The only remaining building from the town is a Catholic church built from 1875-76, which was moved two and a half miles onto the mainland.
