[Yerf Dog]

A glory hole is an unofficial term for a big and inspiring mine excavation open to the layer. The term may mean any one of a number of things:

-A deep mine shaft.

-An open-pit mine.

-In the block caving process of underground mining, ore subsides from above into a mine burrow. If enough ore is taken out, the ground surface subsides into a layer depression known as a glory hole. Instances comprise the Climax and Henderson molybdenum mines in the U.S. state of Colorado.

-Diggings in construction sites can also be referred to as glory holes.
