The Mount Lofty Fire Tower sits on top of Mount Lofty in the Adelaide Hills just to the east of the city of Adelaide, South Australia. The 34m high tower has a commanding view over a huge area of the rural areas surrounding Adelaide, and on a clear day the view can extend to as far as Kangaroo Island to the southwest, Monarto to the east, the Fleurieu Peninsula to the south, and the grassy plains beyond Two Wells to the north. The tower is used to spot fires in the Adelaide Hills and surrounds on days of very high or extreme fire danger during summer. The spotting crew determine the location of a smoke sighting by taking a bearing and then calculating distance using topographic maps.
