The GEM of Egypt was a power shovel used for strip mining. Built in 1966, the machine had worked in the Egypt valley coalfield, the GEM acronym standing for Giant Earth Mover. It was only one of two Bucyrus-Erie 1950-B shovels built and one of two to use the knee action crowd[clarification needed]. The machine began work in January, 1967 for CONSOL (Consolidated Coal) in the "Little Egypt Valley" near Barnesville, Ohio. The machine was parked in 1988 and finally scrapped in 1991. Parts of the shovel were used to keep its twin, The Silver Spade, operating until it too was retired.
