Discovery Rupes

Discovery Rupes is an escarpment on Mercury approximately 650 kilometers (400 mi) long and 2 kilometres (6,562 ft) 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. It was discovered by Mariner 10.
