Lightning Ridge was named after an event that occurred in the late 1800s, when a flock of 600 sheep, the shepherd and his dog were killed by a lightning strike on an ironstone ridge. Here are some extra photos from behind the scenes of the IDU video about Lightning Ridge's unusual name:

Above: Various photographs in and around Fred Bodel's camp, one of the oldest remaining structures in the Lightning Ridge area, and the only remaining building in the old Nettleton settlement on the Three Mile field. Note the materials used to construct the shack: local stone, corrugated iron scraps, pressed tin sheeting, timber "props" (straight logs used to support the ceiling of opal mine tunnels). Inside the hut's two rooms we find a bedroom with carpet floor laid directly on the dirt, a sitting area with fireplace and mantel, and a kitchen stocked with period items (the fly spray may be more modern).
