Fourteen Foot Shoal Light
The lighthouse at Fourteen Foot Shoal was named to note that the lake is only 14 feet (4.3 m) deep at this point, which is a hazard to navigation, ships and mariners.

This light is located at the northern end of Lake Huron, Michigan, US, where it is necessary for boats heading to Chicago to pass through a narrow strait and still avoid shallow water. The most common path is to go south of Bois Blanc Island (Michigan). In this channel, the Poe Reef Light marks the northern end of the safe channel and the Fourteen Foot Shoal light marks the southern side of the channel.
