About Enterprise Rupes
Enterprise Rupes is the largest lobate scarp on Mercury, a cliff about 820 to 1,000 km (510 to 620 mi) long with more than 3 km (1.9 mi) of relief. It is a thrust fault: as Mercury's interior cooled, the planet shrank and its crust broke and pushed up along faults like this one.
The cliff cuts across the rim and floor of Rembrandt basin, about 715 km (444 mi) across, which makes it younger than the basin. It forms the northern wall of a great valley on Mercury about 400 km (250 mi) wide. It is named for the American steamship Enterprise, which explored the Mississippi, Amazon and Madeira rivers and sailed on a worldwide survey from 1877 to 1886.
