Discovery Rupes is an escarpment on Mercury approximately 650 kilometers (400 mi) long and 2 kilometers (6,562 feet) high, located at latitude 56.3 S and longitude 38.3 W. It was formed by a thrust fault, thought to have occurred due to the shrinkage of the planet's core as it cooled over time. The scarp cuts through Rameau crater.
