Rupes Tenuis (Latin: thin cliff) is a Martian north polar scarp.[1] It is named after one of the classical albedo features on Mars.[2] Its name was officially approved by IAU in 1988. It extends from latitude 74.94°N to 82.2°N and from longitude 242.12°E to 300.77°E (59.23°W – 117.88°W).[2] Its centre is located at latitude 81.6°N longitude 85.47°W.[2] It marks the outer perimeter of Planum Boreum from longitude 242.12°E to 300.77°E, and it is formed by the eastern extension of the Olympia Cavi, a series of local troughs and depressions, which become longer and deeper as they merge to create the Rupes Tenuis scarp formation.[3] The scarp is located to the west of Chasma Boreale, at the base of Planum Boreum,[4] and its height varies from a few hundred metres to a maximum of approximately 1000 metres.[4][5][6]
