Environmental and landscape photographer Tom Gill has been documenting the natural and man made wonders of the southeastern area of Lake Michigan, in particular lighthouses. During winter these lighthouses become barely recognizable as spectacular frozen ice formations turn them into incredible sculptural forms. Gill’s favorite lighthouse is the 35-foot St. Joseph that was first built in 1844. The lighthouse would often receive a thick layer of ice during winter storms when freezing waves up to 6 meters tall crash into the piers. The air temperature drops 20 degrees below zero.
