Sand Heads marks the northern entrance to the main channel of the Fraser River. The position of Sand Heads was ever changing due to the roughly 20 million tons
of sediment that the Fraser River empties into the Strait of Georgia each year.1
Scott describes Sand Heads as a nightmare for mariners.2 In 1859, gold prospectors demanded a light at the river mouth, but it was not until
1865 that the government purchased a vessel and anchored it offshore to mark the safe
route upstream.3 Later, in 1879, a unique lighthouse was built, one of twisted iron poles driven deep
into the silt and topped with a wooden lighthouse tower.4 As the entrance to the Fraser River shifted over the years, more lighthouses and anchored boats were used to mark the
safest entrance.5
