The Bullion Pit, west of Williams Lake, was once the largest hydraulic placer mine in the world. In all, some 200 million tonnes of dirt and gravel were washed away to create a huge chasm more than 250 metres wide, 120 metres deep, and 1.6 kilometres long.
It operated from the 1860s through to the 1940s and while it is no longer operating, the massive trench remains.
