GLORY HOLE:
This is a more general excavation and mining term, rather than one exclusive to gold mining. A glory hole is a big, impressive-looking excavation that's open to the surface. It can be either the top end of a deep mine shaft, or an open-pit mine. Sometimes a mining process called block caving, in which ore is removed from a tunnel, causes the underground excavation to collapse, forming a glory hole. In typical alluvial gold mining, it can also refers to the eroded out depression formed at the base of an ancient waterfall. Because this concave geometry is known to be ideal for gold concentration, these glory holes are much sought after deposits.
